Not really, if you're being pedantic. Web 3.0 was used by Tim-Berners Lee to describe Semantic Web as it was meant to be "Web 2.0 + Semantic Web = Web 3.0", while Web3 (notice lack of space + lack of ".0") was coined by Ethereum (and Gavin Wood if I'm not mistaken) to describe it's client SDK/API for it's users.
Web 3.0 didn't go anywhere, and Web3 has now seemingly changed meaning from Ethereum API to whatever the word means now (which seems to be different depending on who you ask)
"Anywhere" is a bit harsh; Google (and seemingly other indexers) honor semantic markup in several contexts via https://schema.org/ -- I would bet that's a large contributor to the "Rich Result" cards that show up in the SERP for sites with such markup.
Separate from other "generic" semantic data markup concepts, JSON-LD[1] is also still making a showing, most commonly (in my experience) as `<script type="application/json+ld">`
So I guess it depends on whether "go anywhere" means "Amazon.com is fully HATEOAS serving RDF, or GTFO" but I would think the actual situation is that it just is taking a while for pointy-haired types to see market value in adopting those concepts, and not so much "what a failure"
