There's a lot of other stuff beyond Ethereum, too. Privacy coins in particular look very little like what was envisioned in Satoshi's paper.
Whether that's all worth anything from an economic perspective, I'm not sure (and even less sure whether it's worth what it's valued), but crypto is legitimately a bunch of very clever technological solutions to hard problems, invented by actual hackers, so I'm a little sad to see people minimizing it on Hacker News.
Especially since this particular innovation is ameliorating the whole global warming problem, which is the prime criticism leveled at crypto. Take that away, and isn't it just open source software that we're talking about here?
