If you want to know where tech is going, watch the kids.

Video game sales were valued at $79 billion in 2017, larger than the global PCB market and growing at about 14% per annum. As far as gaming hardware is concerned, combined sales of pure game consoles and high-performing PC graphics cards for gaming generate about $50 billion each year.

Short product lifetimes mean gaming hardware is a constant revenue driver. In addition, gamers’ demands for more lifelike experiences have driven rapid technological change, including the development of dedicated high-performance graphics processing units (GPUs), which first emerged in the late 1990s.

The GPU was initially conceived to boost 3-D graphics performance, taking on specific workloads such as triangle calculation. As GPU capabilities have increased, game designers have increased the complexity of their scenes to ensure ever-greater realism. Ultimately, of course, the benefits of this “arms race” have transcended the gaming community: GPUs are now found to be remarkably adept at taking on performance-hungry workloads such as AI acceleration and blockchain mining, tasks that much of today’s world depends on but that could barely have been on researchers’ radars when the first GPU chips hit the market.

Between counterfeits and improper handling, the potential for consequences is rampant.

I’m a huge fan of the connected world. I’ve commented previously on the many potential benefits for communities everywhere. Like many good things, however, it poses its own set of challenges. One of these is the “democratization” of cyber-crime. The spread of the IoT means we are all vulnerable in our connected homes, our connected cars, or when enjoying the efficiencies of connected infrastructures and smart services. The potential consequences of cyber-attacks are no longer an issue only for banks, governments or large corporations. The consequences of a hacked car or medical device can be personal, real-time, and in some instances life-threatening.

IoT software protocols and hardware-device security down to the silicon level are being developed to counter a host of potential attacks that can range from stealing stored passwords or intellectual property to taking over devices and systems using malicious firmware. This will be an ongoing battle of “arms versus armor.” Other potential security threats such as counterfeiting are more mature, less fast-paced, but costly and potentially dangerous. Counterfeit electronic components are reckoned to cost the industry billions of dollars every year, although the Semiconductor Industry Association points out that the safety implications and potential threat to life posed by rogue components often worth only a few cents each make this a far more serious issue than financially larger black markets such as those for counterfeit high-value luxury goods.
