MediaWiki is certainly future proof and has lots of inertia, including a large API surface area, a large ecosystem, and the backing of a deep-pocketed benefactor. An extremely underrated/largely unknown project is Miraheze[0] which is a non-profit that provides free MediaWiki instances to people.
I wish proper wikis hadn't gone by the wayside. (I think it has a lot to do with MediaWiki's default skin being out of style, and people not realizing they can change it.) Most of all, I wish open source projects would stop dumping a bunch of Markdown in a repo somewhere and calling it a "wiki". They're not even close to comparable.
My two biggest complaints about MediawWiki are 1. PHP, and 2. no well-supported way to opt-in to a different syntax like Markdown or AsciiDoc or pretty much anything that isn't MediaWiki-flavored wikitext.
