Exclusive Hands-on Review of the new Verve Infocrank Power Meter

first_imgOur goal with the growth of the power meter market was to see how a typical rider might set up and use the Infocrank. The test unit we received was already installed, but we needed to set up a couple of GPS head units from scratch. We first started with the new Verve-branded Navi2coach that comes with the Infocrank, and while its user interface seemed to take a little while to get the hang of, pairing the power meter was easy and straightforward. What was a bit more complicated was setting up the workout displays. O_synce has a nice looking piece of software called trainingLab to adjust the settings from your home computer, but unfortunately it is not Mac-friendly so I stuck to doing everything through the GPS’s interface to see how easy it would be. (Verve Cycling has a pretty useful video tutorial on their youtube channel that shows you how to set up the display pages with Training Lab, and also offers some good insight into which metrics will be helpful for on-the-bike training.) With only four navigation buttons and abbreviated menu titles it took several minutes to get all of the metrics I wanted displayed, but once set up it functioned flawlessly. As a comparison, I also paired the power meter to a Garmin Edge 800, which was also simple and a bit quicker using an interface I was more familiar with.Even though we didn’t need to install the crankset, a quick removal/reinstall via its self extracting bolt to weigh the system showed me that regular users should have no problems with installation. It is if anything more straightforward than many cranksets on the market. Plus, Verve has prepared a very concise and helpful set of installation videos on their youtube channel that should alleviate any concerns. Tech Details & Actual WeightsOne of the first things to notice is that Verve focused their involvement on what they do best and that is the technology of building a high quality, precision power meter directly integrated into the load path of their own optimized crankset design. From the beginning Verve honed in on the science behind power metering with a single goal to “measure power accurately”, something they were disappointed to discover was not easy to find on the cycling market where in-lab and real-world results didn’t always agree or remain consistent.Verve pairs their base cranks with the exceptionally well received Praxis Works forged chainrings and a Praxis bottom bracket (M30 or BSA) leaving those parts to the specialists. They also includes the Navi2coach head unit from German company O_synce (something of an analogue to the Garmin 500) where they were able to have greater input into the development of the user interface and the use of key bilateral metrics. From a functionality perspective the Infocrank was easy to use and worked perfectly through our test. I also certainly appreciated the inclusion of well-trusted parts from Praxis, which ensured good stiffness and excellent shifting that simply disappeared under pedal.The oversized forged crank arms themselves seemed stiff enough, as does the 30mm spindle, although probably not quite as stiff as a pair of high-end carbon cranks. The bike I tested had a traditional threaded BB, and unsurprisingly the PF/BB30 systems are rumored to be even stiffer. The 694 gram-claimed Infocrank is a forged 6000 series aluminum crankset with an integral 110 BCD compact spider and machined recesses in each arm housing individual left and right power metering modules.The cranks are available in 170, 172.5, and 175mm lengths, in a black anodized finish.The Praxis chainrings are offered in either 50/34 compact or 52/36 semi-compact.The 30mm Praxis bottom bracket is compatible with either BSA, BB30, PF30, or BB86 frames.Our sample setup weighed 871g total including the 135g Praxis rings, 10g chainring bolts, and 30g magnets (just 2 grams heavier than the claimed weight.) As we introduced them to you this spring, Verve Cycling is now delivering the production version of their new power metering crankset, the Infocrank. The power meter can now be ordered online, and is shipped consumer-direct from either their EU, US, or Oceania distribution hubs. Then through a network of worldwide Affiliates, they can work with you to make sure you take full advantage of the power meter’s training capabilities.Having recently finished final beta testing and now been delivered to early supporters, we had the unique opportunity to borrow a set of the power metering cranks directly from Verve Cycling’s president for just over a week to see what customers could expect. Bryan Taylor lent us his personal Cervélo R3 with the Infocrank installed while he was traveling on business, giving us a chance to go through the new setup process with the included O_synce Navi2coach GPS computer, as well as to pair it with a standard Garmin Edge computer. We tested out the cranks on a few regular mid-length group and solo road rides, as well as giving it a go on some gravel, and even a bout on the indoor trainer. The goal was less about testing the accuracy of the power meter (a point where Verve seems to excel, btw) and more about how a rider might set up and actually use the Infocrank.Come past the break for the full details and real world weights. Paired with the included cadence magnets (both BB cup mounted magnets like we used and an adhesive-mount magnet are included), the crank translates direct torque (Nm) measurement into power (W) and includes cadence (rpm) tracking. With left and right measurement the Infocrank allows power balance analysis, as well as per pedal torque and pedaling efficiencies not often tracked by other power meters.The Navi2coach computer is fitted with a 4-point 1/8 turn locking mount exclusive to Verve (and similar to but not compatible with Garmin’s 1/4 turn Edge mount). The Verve-branded computer includes a rubber band handlebar/stem mount and a Barfly out front style mount for 31.8 bars.A unique feature of the Infocrank is the configuration and factory calibration of the strain gauges directly in the load path between pedal input and crank rotation, meaning there is no need to ever recalibrate the crank during normal use, greatly simplifying operation versus the competition and removing a common opportunity for user error. The design and layout of the strain gauges automatically eliminates data drift over time, compensating for temperature and pressure changes, ensuring that it reliably measures power in all conditions. As a result,  Verve is very adamant in reminding that the “accuracy of an InfoCrank will not change over time. This means you DO NOT need to Calibrate using your bike computer, ever.”The Infocrank power meter was developed in collaboration with the Australian Institute of Sport, who has been responsible for testing accuracy and drift, the defining hallmarks of the Infocrank. By incorporating a Wheatstone bridge arrangement of its strain gauges not sensitive to drift, Verve quotes a resulting accuracy of ±0.2 Nm < 20 Nm and ± 1% > 20 Nm.That means ±1% for measurements of about 160W and above, while independent tests have measured the max deviation of just over half of that.With variation regularly ±10% between many of the current power meters on the market, the Infocrank may be a market leader in terms of true accuracy. Always concerned with real-world accuracy, Verve’s head engineer put together a short manifesto on “Why a power meter that’s relatively good is just not good enough.“ Have a look there for an interesting read on the science behind the Infocrank.Data transfer is wireless by the ANT+ standard allowing pairing with almost any cycling computer, although not all on the market can benefit from full bilateral data streams. Each power measuring module is powered by a user-replaceable button cell battery with a 500 hour operational life.Verve works closely with their Affiliate network to continuously develop and deliver firmware updates to incorporate added functionality with the latest ANT+ protocols to meet end user needs. Also working with computer provider O_synce, they are one of the first systems to include the newly developed bilateral Torque Efficiency (per pedal) and Pedaling Efficiency (per pedal) protocols.Pricing for the complete power meter is 1533€/1260£/$1750/A$1999, depending on your market.It includes a set of forged Praxis chainrings, a Praxis bottom bracket, the Praxis BB installation tool, both stick-on and BB-mounted cadence magnets, and the O_synce Navi2coach GPS head unit. All Infocranks include a 2 year warranty.center_img Initial Setup Ride ReviewFor our short test period the weather faired well, so we didn’t get past dusty gravel roads and the occasional puddle to see how the power meter stood up to the elements. Verve does recommend against direct pressure washing as is standard for power meters, but the crankset is IPX7 rated (to 1m) so water infiltration won’t be a regular concern. The flush installation of the power metering modules inside of the stout aluminum arms should also keep the sensitive parts safe. One minor concern we might have is that these power metering modules are located on the crank arm where heel draggers tend to scuff their cranks. It is likely not a concern (again being flush, or actually very slightly recessed, and protected by the aluminum arms), but if you pedal with heels in it would probably be worth keeping an eye on the covers over time for any significant wear. Now with all of the data generated and the repeatability and accuracy that Verve is promising, someone seriously training or racing at a high level could really benefit from some deep data analysis. One of the simple uses of all that power data is to passively drop it all into some training software like Training Peaks, Golden Cheetah, or even Strava to quantifying each ride’s Training Load which can help track your fitness over time and even plan rest periods. But to truly benefit from that rich data I think you would really need to combine the power meter with a professional coach and a full-time training schedule. That is one of the potential great benefits of Verve’s Affiliate program. These training professionals with expertise on the Infocrank can help you decide if you want to make the jump from amateur cyclist and data collector to a serious competitive cyclist with their further services.I personally feel like detailed power at my fingertips is more than I need, until I decide to get a bit more serious with training. I imagine that when cyclocross season comes around I’ll realize how much it would have helped me, so until then I will just need to find a more competitive friend to buy an Infocrank that I can borrow a couple of times a year to benchmark myself. Actually, I think I already have someone in mind.VerveCycling.com I was surprised and sometimes annoyed at how slow the Navi2coach was to pick up a GPS signal here in central Europe compared to the Garmin 800, which tends to be slow itself, even after having been used for several days at the same start point. The 800 sometimes took 10 seconds more than a Garmin Edge 200 I had on hand, while the Navi2coach was up to 25 seconds slower. While just an annoyance, my impatience meant that data collection started a couple hundred meters after I started each ride. Of course you could start without a GPS signal, and I had no problems collecting power, heart rate, and cadence data when riding inside on the trainer.Subjectively, we got a lot of curious and strange looks from those we rode with. Some thought the crankset looked very bulky or too angular, while I personally like its somewhat industrial aesthetic. Even though the Navi2coach computer was totally functional, the lack of real mapping or a touchscreen interface were turnoffs for me, and being used to an Edge 800 I would prefer to have the power meter offered individually. I am a big fan of compact cranks, but again I was asked why it doesn’t come in a standard road 130BCD since that’s what most ‘racers’ use. I don’t have much of a response to that except to say Verve is working on it, so keep your eyes open for news in the near future.With all the live power data on the display, the right/left power balance feature was certainly interesting to watch. I was most intrigued how my power output, both instantaneous and 3-5 second averages, stayed very unbalanced depending on which leg I started with for a hard sprint or out of the saddle climbing effort. It led me to look at how to be smooth more quickly after that first big pedal stroke. But in general seeing as how my overall power output was pretty well balanced (within 5-10% on average), there really wasn’t a real benefit for me vs. having only single sided measurement.In the end what did I think about having real accurate power displayed at my fingertips?Well, as someone who only begrudgingly trains part of the year so that I don’t suffer on a few key events and then again through cyclocross season, I think detailed display of the data was distracting. Unless you train with power year-round, real live power output is just an abstract number, and over the top for most users. It was nice to have the power balance numbers and the 3 and 30 second averages to show me what my real power output was on some familiar extended climbs and flat Strava TT segments, but the amount of data you can display is pretty overwhelming. I think in setting up the computer, simplicity in what you display is key.last_img read more

Study fails to link conspiracist thinking to a biased perception of randomness

first_imgLinkedIn Pinterest To investigate the relationship between conspiracist beliefs and perceptions of randomness, the researchers designed three separate experiments in which participants were asked to look at strings of 12 Xs and Os that supposedly represented a series of outcomes.In the first experiment, 107 university student participants were told that some of the strings were created using a fair coin and were, therefore, random; they were also told that other strings represented non-random outcomes, such as computer calculations or a sports team’s wins and losses. The participants were presented with a series of 40 such strings — for each one, they were asked to rate the randomness of the string on a scale of 1 (certainly random) to 6 (certainly not random).In a purportedly unrelated “translation” task, participants completed measures that gauged their general belief in conspiracy theories, their belief in specific conspiracy theories (such as the Apollo 11 moon landing), and their perceptions of conspiracy in certain scenarios.The results showed that participants’ responses on the conspiracy theory measures were correlated — in other words, participants who reported a strong belief in general conspiracy theories also tended to report other types of conspiracist beliefs.But, the researchers did not find any evidence to suggest that people who tended to believe conspiracy theories were more likely to see intention or design in the letter strings.A follow-up study with 123 university students and an online study with 217 adults showed the same pattern of findings — while participants’ conspiracist beliefs in one area were associated with conspiracist beliefs in another area, there was no evidence to suggest that believers were biased toward seeing intention in the letter strings.And all three studies indicated that participants were sensitive to the complexity of the strings — for example, they tended to rate the string XXXXXXXXXOOX as less random than the string XOOXOXOOOOXX. These results align with the probability that a randomly chosen algorithm would produce the strings, suggesting that the participants were attuned, in some way, to the likely randomness of the strings.“Conspiracy theories are now widespread and they develop increasingly faster, sometimes minutes after a dramatic event,” says Dieguez. “Research has shown that they affect health decisions, political and voting behavior, reliance on science, and underlie many extremist and violent actions. Our research contributes to understanding the psychological and social mechanisms that do — or, in this case, do not — facilitate their endorsement and spreading.” Email Share on Twittercenter_img Share In pop culture, conspiracy believers — like FBI agent Fox Mulder on The X Files or professor Robert Langdon in The Da Vinci Code — tend to reject the notion of coincidence or chance; even the most random-seeming events are thought to result from some sort of intention or design. And researchers have suggested that such a bias against randomness may explain real-world conspiracy beliefs. But new research from psychological scientists at the University of Fribourg and the University of Paris-Saint-Denis shows no evidence for a link between conspiracist thinking and perceptions of order, design, or intent.The findings are published in Psychological Science, a journal of the Association for Psychological Science.“We could not confirm our initial hypothesis that the tendency to reject randomness, or to perceive order and meaning where there is only noise, was associated with the endorsement of conspiracy theories,” explains lead researcher Sebastian Dieguez. “Although negative findings are usually unpopular in scientific journals, we think our results are valuable because they contradict a widely held and quite plausible idea of what leads to conspiracist thinking. By ruling out a very straightforward and cognitively simple mechanism, we narrow down the range of explanations for the popularity of conspiracy theories.” Share on Facebooklast_img read more

ARKLESS DEMANDS THE DETAIL ON DEMENTIA CARE FROM THE HEALTH BOARD

first_imgAddThis Sharing ButtonsShare to FacebookFacebookFacebookShare to TwitterTwitterTwitterShare to LinkedInLinkedInLinkedIn Local MP Richard Arkless has demanded that the Dumfries & Galloway Health Board show the people of Wigtownshire the ‘detail’ of the plan of what will replace Darataigh, the intermediate Dementia Care Centre in Stranraer facing closure.Mr Arkless said:“The Health Board are telling us that they will replace Darataigh with better care in the community and more availability in Care Homes – but we are yet to see the detail of that plan. Something which I find unacceptable given the circumstances.”In his letter to Jeff Ace the Chief Executive Mr Arkless said that affected families, staff and members of the public need more information than ‘the vague briefing initially provided’ by the Health Board. He added that he had spoken to some of the units staff and patients and none of them were aware of any detailed plans; they have been left in complete limbo.Darataigh closed suddenly in November 2015 following the failure of a boiler unit. The dementia patients were then transferred to Midpark Hospital in Dumfries, 72 miles away. Following a public outcry at the abrupt closure of the unit, the Health Board repaired the boiler and said that Darataigh would remain open for a further six months.However, since November no patients have been returned or referred back to the unit and more and more intermediate care services are being made available at Midpark in Dumfries.In his letter Mr Arkless demanded that Mr Ace answer some key questions including:“How much money will be freed up by the units closure and how will this be redistributed? How will we beef up the care teams and wider access to care in the community? What are the plans for each of the staff? We are beyond the point of vague principles, we need the detail.”Mr Arkless added:“The Health Board is embarking on a steep uphill struggle to convince the people of Wigtownshire that the decision to close Darataigh is the correct one.“I along with local councillors and elected members of both Parliaments, remain completely unconvinced of Mr Ace’s plans and remain determined to fight them.“I am particularly concerned as members of staff have informed me that they have little or no knowledge of the detailed plans and arrangements surrounding the closure of the unit or their future – nor have I.“A proper consultation period with all affected parties must begin in earnest and dementia patients should be referred there instead of spending extra time in Dumfries. The staff at Darataigh are incredible, and if anyone can input experience into these plans, it is them.”Mr Arkless concluded that a detailed plan of the future of community based mental health care provision in Wigtownshire must be circulated to all parties concerned as a matter urgency.last_img read more

Tottenham move up to third, Cardiff closer to relegation

first_imgKane is expected to miss the rest of the season due to ankle ligament damage suffered during Spurs’ 1-0 win over Manchester City 1-0 in the first leg of their Champions League quarter-final.Dele Alli was also sidelined by a broken hand, while coach Mauricio Pochettino took the chance to rest some other key personnel such as Son Heung-min ahead of the second leg against City on Wednesday.Lucas took his chance to shine against the already relegated Terriers to show Pochettino he could be an important weapon in Kane’s absence as Spurs look to tie down a top-four finish and a place in next season’s Champions League.“Players need to play to show their quality. The hat-trick is going to build his confidence,” said Pochettino.Victor Wanyama opened the scoring on 24 minutes to allay any fears that Tottenham might suffer a European hangover.Lucas made it 2-0 three minutes later and then struck twice more in the final three minutes as Pochettino’s men made it three wins from three at their impressive new 62,000-capacity home.And Pochettino was delighted to see his side rack up the score in the final stages with goal difference potentially pivotal come the end of the season.“It is going to be a very tough race. To score several goals is important. The goal difference can be decisive to achieve the top four at the end,” added the Argentine.Tottenham move a point clear of Chelsea, who travel to title-chasing Liverpool on Sunday, while fifth-placed Arsenal are now four points adrift of their north London rivals but have a game in hand at Watford on Monday.– Controversial Cardiff defeat –Chris Wood scored both goals in Burnley’s 2-0 win over Cardiff.

A Coke Machine, A Dorm Room, A Gate: How NFC Will Be Adopted

first_imgWhenever people think of near field communications, they think of mobile payments. Your phone becomes your wallet and spending money becomes as easy as tap, tap, tapping all day. Well, the era of your tap-able digital wallet is not here yet. It may never come. But that does not mean there are not some very interesting uses of NFC coming down the pipeline.For instance, there was a Coca-Cola vending machine at ad:tech this week that was tied to Google Wallet. Tap, tap, tap away and take a Diet Coke Break. At Nokia World there as a gate that could be opened with a tap from your phone. A developer is working on NFC solutions to help his father who has Alzheimer’s. NFC could be great as a monetary transfer solution, but there is so much more. Groundswell To An NFC Enabled WorldA couple of months ago we wrote about a pilot program at Arizona State University gives students NFC-enabled phones that can be used to access dormitories and university buildings. At the time we said that this is the perfect place for the widespread use of NFC to start: universities have long been known to be the birthplace of behavior-changing trends. Let’s look at the NFC Coca Cola machine. This is actually the second time that we have run across one of these prototypes (note: we were not at ad:tech this week but found this story from Mobile Commerce Daily). The first time we saw one of these Coke machines was at a reception around mobile payments from MasterCard in New York City a couple of months ago. It functioned just like any other Coke machine, except it accepted money through NFC. Make your selection and tap on the receiver instead of digging through your pocket for change. “The combination of mobile commerce and location technology moves our business from the point of sale to the point of thirst,” said Wendy Clark, SVP of integrated marketing communications and capabilities Coca Cola according to Mobile Commerce Daily. “We have to place bets and we have to take risks if we want to feel innovation in the way that we market.” Why IoT Apps are Eating Device Interfaces We may see groundswell coming from the big brands that are looking to change how they interact with customers. NFC is not going to be adopted because the big corporations like Google make partnerships with other big corporations in the mobile and financial worlds and all of a sudden we are going to change how we go about our day-to-day lives just because they tell us so. The act of buying a Coke is one of the simplest and most straightforward acts in all of society. If you see that your friend just paid for a Coke at a vending machine with her smartphone, you are much more likely to go, “hey, I wonder if I can do that to.” Once you have your foot in the door, you are more likely to use that process again.Adapting Technology To The SituationDuring Nokia World in London I met a developer that wanted to explore NFC because his father has Alzheimer’s and he wanted to figure out how the technology could help him give his father a way to manage his day-to-day life. For instance, setting timers on items around the house to keep his father from doing odd things at odd moments, like opening cabinets in the kitchen at 4:00 a.m. or leaving the house at the same time and wandering the neighborhood, not knowing where he is going. If his father has a watch with NFC in it, he could program those household functions to only respond to the NFC timer at certain times of the day. This was all in the theoretical stage as the developer was just starting his initial research but those types of capabilities are not beyond the realm of NFC. Think of it: this is how NFC will evolve. Consumers are not going to be bludgeoned from on high by companies like Google, Sprint and MasterCard. It will start as a groundswell where developers see a problem, solve a problem. Big brands, like Coca Cola or Wal-Mart, will start instituting NFC solutions and people will become familiar with the technology first. It is one thing for Google to have a big demo, roll out a bunch of partners and say “this is the future.” It is another for people to actually have the technology in their hands, using it to do a variety of activities. Even the Google Wallet competitor, ISIS, thinks that competition is good for the realm. In an interview with CNET, ISIS CEO Michael Abbott said, “competition is what this space needs.” Why would he say something like that? Because Abbott understands that people learn from other people and that the more solutions there are out there for people to see the technology in action, the more will ultimately adopt it. Competition drives innovation and better products in consumers’ hands. In that way, the technology adapts to the situation, not the situation to the technology. What do you think are the possibilities of NFC? Can you see it being more than just a clever way to pay? Let us know in the comments.

Accelerating Deep Learning Workloads

first_imgAt the International Supercomputing conference this week in Frankfurt, there’s a lot of excitement about new technologies that are fueling the momentum of artificial intelligence and deep learning, which is now used across a wide range of industries. Intel offers a wide portfolio for all AI segments, including our upcoming Intel® Xeon® Processor Scalable Family and Intel field programmable gate arrays (FPGA).  This excitement extends to the upcoming Intel® Xeon Phi™ processor, code-named Knights Mill, which will take deep learning systems to a new level.This new extension of the Intel Xeon Phi family, expected to be in production in the 4th quarter of 2017, is specifically optimized for deep learning training. The processor is designed to meet the unique needs of data scientists, engineers, and others focused on the application of machine learning technologies. In particular, Knights Mill is designed to reduce the time to train deep learning models by taking advantage of low precision computing.So why does low precision matter? In simple terms, data scientists need hardware that can accelerate convergence when training models. In the past, deep learning models could take days or weeks to converge on one iteration. That makes it very difficult for data scientists to perform research in an appropriate amount of time.Today, current hardware can reduce this training time down to a matter of hours by using lower-precision computing — which equates to faster computing. As long as the hardware meets the accuracy requirements of the deep learning framework, what is important is how fast the hardware can train the model. This is why lower precision is usable for deep learning workloads and is the preferred computing method in comparison to HPC, which typically requires single or double-precision performance.So what’s the difference between Knights Mill and the current Intel Xeon Phi processor, formerly code-named Knights Landing? This is a question we hear often from customers who are focused on HPC, AI, and machine learning.Knights Mill uses the same overarching architecture and package as Knights Landing. Both CPUs are a second-generation Intel Xeon Phi and use the same platform. The difference is Knights Mill uses different instruction sets to improve lower-precision performance at the expense of the double-precision performance that is important for many traditional HPC workloads. This means Knights Mill is targeted at deep learning workloads, while Knights Landing is more suitable for HPC workloads and other workloads that require higher precision.As for those different instruction sets, they are called Quad Fused Multiply Add (QFMA) and Quad Virtual Neural Network Instruction (QVNNI). QFMA is a process that doubles the amount of single precision performance that Knights Mill can deliver over Knights Landing. QVNNI is a process designed to lower the precision even further while still meeting the accuracy requirements of deep learning frameworks. The net effect of doubling single precision performance and reducing precision further enables Knights Mill to deliver significantly more performance for deep learning workloads, in comparison to Knights Landing. There are also frequency, power, and efficiency enhancements as well, which contribute to this performance increase, but the instruction set changes offer the largest performance increase.To take a step back, the Knights Mill processor isn’t only about accelerating deep learning workloads. It’s about gaining new processing capabilities within the context of your existing Intel-based environment. Intel Xeon Phi processor platforms are binary-compatible with Intel® Xeon® processors. Almost all workloads that run on Intel Xeon processors will run on Intel Xeon Phi processors. This makes it easier to share your software investments across Intel platforms.At another level, Intel is unifying the way forward for deep learning practitioners to use deep learning frameworks across hardware platforms. These are among the benefits of Intel® Nervana™ Graph, which brings advanced capabilities to deep learning frameworks. This computational and execution graph for neural networks allows developers to automatically apply optimizations across multiple hardware targets allowing users to share their software investments across different Intel platforms.If you’re at the ISC conference this week, you can learn more about Knights Mill and Intel’s AI portfolio in the Intel booth.

Internal CSIS note details mega trends set to alter economy society security

first_imgOTTAWA – From cryptocurrencies, to artificial intelligence, to the rise of millennials, a top-secret document by Canada’s spy agency explores the so-called “mega trends” on its radar and details how they will transform the economy, society and security.The evolution of these trends — set to play out over the next five to 15 years — will unlock new opportunities and new threats, said the recently released document prepared for Michel Coulombe, who was director of the Canadian Security Intelligence Service at the time.The draft discussion paper was created ahead of Coulombe’s participation at a November 2016 deputy ministers’ committee meeting on national security.In the briefing, CSIS officials shared their insights on cyber security and privacy, the economy’s evolution toward knowledge-based sectors, the arrival of blockchain and cryptocurrencies, artificial intelligence, the emergence of the millennial generation, encryption and the advance of quantum technologies.“Each of these trends bring promise and challenge,” said the paper, which was labelled “top secret.”“The rate and impact of technological advances and interactions are often misunderstood or underestimated. Organizations — faced with time, money and people constraints — will struggle to make effective planning and investment decisions.”It warned that significant and sustained leadership, innovation, partnerships and investments will be necessary to deal with the complexity and accelerated pace of these changes.A take-home message of the document is that policy-makers must figure out how much they really know about these disruptive technologies, their potential national-security risks and how to ensure Canada stays secure and prosperous.The briefing was obtained by The Canadian Press under the Access to Information Act.A few areas highlighted on the CSIS list have already attracted some commitments from the federal government, while Ottawa insists others, such as the expected job-killing disruptions of technological change, remain a key focus as it prepares its spring budget.Finance Minister Bill Morneau has said his upcoming budget will have core themes that include finding ways for science to help the economy over the long haul and preparing workers for the rapidly changing job market from advances like automation.A recent report by Morneau’s economic growth council recommended Ottawa introduce new measures to help Canadians acquire new skills to prepare for the labour-market impacts of new technologies.Among the group’s suggestions, it argued that Canada urgently needs another $15 billion in annual investments by 2030 for adult skills development to help workers adjust to the coming changes.The CSIS document also warned that, as the world’s knowledge-based sectors evolve, we should expect increasingly fierce competition as states, organizations and individuals target new expertise and intellectual property belonging to others. It called this information, which would mostly exist in electronic format, a “highly valuable commodity” that will need protection from cyber attacks.The federal government is planning to release a national IP strategy in the coming months. In last year’s budget, Ottawa said the strategy would promote the development of new ideas and technologies by helping ensure companies, academics and inventors reap benefits from their investments.The document also pointed to a group of major technologies that promise to bring profound change, such as AI, advanced robotics, nanotechnology and biotechnology. At the same time, however, it cautioned these developments will likely lead to the creation of “new actors.”“These include state-run laboratories, corporate investors, (do it yourself) maker groups, terrorists and organized criminals that are competing to harness and leverage these technologies in pursuit of their interests,” it said.The paper underlined many broader risks associated with these technologies — from increased susceptibility to cyber attacks, to the facilitation of foreign weapons systems, to unemployment, to AI complications and the related liability issues.The document also examined blockchain technology, the distributed ledger underpinning cryptocurrencies like Bitcoin. The document said if done right, blockchain could become the “plumbing” for all transaction-based systems, including those for government services, heath records and real estate.Looking at the impact of demographic shifts, CSIS said millennials will be the architects of much of this social, political and technological disruption — which means organizations must be ready to adapt, hire and retain them.“The next anticipated cycle will be spurred by the millennial generation who, raised in a technically rich environment, have the potential to launch the next industrial revolution and create an economic boom rivalling — if not surpassing — the one created by the outgoing (baby) boomers.”Follow @Andy Blatchford on Twitterlast_img read more
