Let me take this opportunity to say "happy birthday Walter Mondale." In my industry, Linux has been dominating in terms of being behind anything that smells like high-performance computing. In my colleagues' industries, it is behind embedded systems for autonomous systems, remote sensing, etc. Most of our day-to-day uses in society are to provide convenience in information sharing (social media, news, uber-style apps, etc). We are still figuring out how to use them, and hence big conventions like the on-going one in Las Vegas where companies are displaying IoT stuff, are taking place. Ironically, all I see is technology being used to promote itself, coming full circle but with little substance. Too many tools to hack with, so little hacking! Perhaps we should go back to books that talk about the grand challenges of past times. People who inspire on the use of computers are people like Stephen Wolfram, where he basically tackles biology with a strange computational approach ("A new type of science" published in the 90s). We used to hack all day (and night) to come up with cool stuff to show our friends. But perhaps we need to stop consuming the information that is coming at us (from computers) and start thinking about what problems we want to see solved. Then, we start hitting keys on the keyboard to make it happen. I have too many hobbies to be the visionary, but I can be easily distracted when stimulated enough to help!
