It's always surprising to me when I see people being nostalgic for the old days. Yes, things seemed simpler, but it was because there was less you could do.
I'll always fondly remember my attempt to get on GeoLink with a 300 baud modem, and then my parents realizing that the long distance calls made it far, far too expensive to use, and returning it. Sure, I was disappointed at the time, but it wasn't too much later that 56k modems existed and we had a local unlimited internet provider. And now it's a fun story.
But I was actually just as frustrated at the time as I am now, but for different reasons. Change exists, and that's good.
I agree that it feels harder to make your mark today. But I don't think it's actually harder. There's plenty of fun things that people would love to see people do. Just yesterday, I found out about the Strudel musical programming language and watched an amazing video of someone making Trance with it. And those kind of discoveries happen constantly now, where they were pretty seldom back 30 years ago.
We're at the point that anyone can make a game, app, webpage, etc if they put enough effort into it. The tools are so easy and the tutorials are so plentiful and free that it's really just about effort, instead of being blocked from it.
I've been saying "we live in the future" about once a month for years now. It's amazing what we have today.
