The proper comparison is with Laravel. How will Laravel fare vs Next in 10 years? Hard to say, they could both be equally legacy by then.

I really hope not, because I really hate how JS has fucked the internet. Just look at how shit the experience on www.reddit.com vs old.reddit.com is. Old uses a lot of JS now, which has made the experience a touch worse, but it still mostly serves a static HTML page. It loads quickly, renders quickly, and lets me do useful preference based things on my end.

I hate what JS has done to the internet, and I think it plays a heavy hand in the internets enshitification.
