I grew up as a eighties tech geek kid. I learned BASIC on a SHARP programmable calculator (https://en.wikipedia.org/wiki/Sharp_PC-1403), then moved on to an Atari 800, then to an Amiga, and finally to a PC. Each of these machines was orders of magnitude more capable than the previous one - you don't have that anymore nowadays. Then in the late 90s there was the Internet, with the promise that you could connect to anyone around the world and the potential to really bring the world together. Well, that didn't quite turn out the way 20 year old me imagined unfortunately. Of course, technological progress is still going on, but it's more "your smartphone can now do what your desktop PC did 20 years ago, or your laptop did 10 years ago". SpaceX rockets look practically indistinguishable from rockets that flew 50-70 years ago. Ok, those couldn't land again, but technological progress has been more of a crawl there (with an unnecessary detour into a dead end called "Space Shuttle"). Same with self-driving cars and other potentially exciting stuff.
