If it's not dead, what's some recent steampunk art you've seen?
Steampunk is alive, but more niche. See https://www.brassscrew.org/ for instance.
I can actually see old school web design becoming an art movement in its own right at some point in the future. Imagining what current and future tech companies would look like built on 90s style web technology is pretty fun.
I think you and I experienced different 90s design aesthetics if a bootstrap looking site with a big hero image at the top evokes the 90s for you.
I hadn't clicked through to that year to see.
That being said, I would assume dead was a reference to out of fashion and sure it is out of fashion, but there are still people that enjoy it as an art. 70's Disco is out of fashion but there are still people making 70's disco music.
So it is indeed not dead, it is just not popular.
