I grew up a bit before that. I'm fortunate to have seen society change from mostly-computer-free to folks swimming in tech.
I've also written about half-a-dozen apps that somebody later took and made into a super cool startup. I don't say that to brag. Ideas are cheap. Execution intelligence is where it's at.
I mention the apps I've written because you really have to establish more context if you're going to lament about tech's coolness death. Is tech not cool anymore? Or is it just not cool to you? I feel like I've written a bunch of cool stuff over the years. It's always been cool to me, for whatever that's worth.
Given that setup, I will answer using my own definition of cool. Software ate the world, and that was awesome. It also had a bunch of side-effects nobody wanted to think about, and that sucked. But because it ate the world, ie became an integral part of human existence, tech became incestuous. It's so prevalent in our daily experience that it became impossible to talk about what might be cool or not.
We ended up with a bifurcation. Path A talks about tech only in terms of people creating and sharing content with one another, whether that's a cat pic or instructions to use CPR to save lives. Path B is just concerned with mechanics regardless of impact: how do we set up that identity server template in kubernetes?
I find the endgame of both sides of this bifurcation to be extremely boring. I can solve most tech problems I'm given using tech. Yay. I can explore creating interesting content in various genres given some rando platform. Also yay. But at some point along both of those paths, it seemed like it became a race to the bottom. It all devolved into mindless, manipulative crap. Even if I became a rock star on the tech path or the content path, so what? There'd be a million new folks coming along next year doing it better, and in 50 years nobody would care.
I decided that to me, it was the visceral feeling of integrating tech with creativity that brought the most life satisfaction. That's the feeling I got when I was writing my first apps for a local business at 16. It was the feeling I had architecting big systems that took off and still provide value. You can't separate one path from the other and expect any sort of long-term satisfaction. At least I never could.
