I watched this show religiously as a kid (by then in reruns in the early 90s), along with Star Trek: TNG, Jeopardy, and playing Civilization for PC. The most formative years of my life were spent absorbing as much science, technology, and history as my growing brain could muster. I think that's why I'd grown up to be so optimistic about the future.

I think there's still a lot of room for optimism, despite all of the pessimism in the media, and I'm not even talking about AI. There are a ton of other things which have benefitted enormously from ubiquitous, efficient, and powerful computing that hardly get talked about anymore, we've come to take it all for granted.
