You can, but it feels that due to the homogenization of modern web, it's kind of a forgotten art that we can never revive. I'm hopeful, but realistic.

Fair enough. It's a problem that probably doesn't need solving either, it was more so just a question of could it, but to your point, it's that barrier of entry that's stopping it, I would assume.

Ideally, a contender would replace all three with one new language. My question is more so why hasn't someone built a contender, but the answer to that is also quite clear.

There isn't one, but even if there was, I'm not sure it could replace the amalgamation of today. It would have to be in parallel, I think.

More vaguely GeoCities, Netscape, etc., and an ability to customize all corners of the internet that were yours to your liking. Just got me thinking if it could ever come back.

That's fair. Maybe it's a nostalgia for Web 1.0, websites being ugly, but personable, that I would even offer the idea.
