The article's list of technologies, at first glance, seems like it has examples from different technologies. But they are all really the latest pieces of the same line of technology: Personal Computing/Internet.

The author (and I'm assuming a lot of people on HN, myself included) came up when the Internet and Personal Computing was growing. The next technology that people are excited about probably isn't the latest in Personal Computing/Internet, it's something else altogether. I'm in the same bubble you guys are, so I'm not sure what that is. Maybe it's Energy (lots of Solid Hydrogen articles and/or Clean Energy). Maybe it's something else altogether...
