I’m a person who knows a lot about how computers and software work, is generally curious, and reads fast. I’ve been wrong about lots of things over the years. But there have a been a few times when a combination of technology-literacy and just paying attention to the world have made me 100% sure that I was seeing something coming that many others weren’t. Here are a few of those stories. The reason I’m telling them is that I’m in another of those moments, seeing something obvious that not enough other people have, and I want to offer credentials before I share it. Also, some of the stories are entertaining.
