Haskell isn't practical for a lot of projects though just based on where your code has to run and what existing libraries you want to use.

Yes. But this is more the problem of vendor lock-in than anything to do with Haskell.

Yeah, not knocking the language. It's frustrating how it takes so long for good programming language ideas to defuse into the mainstream. It's crazy how strong type systems have been around for literally decades and we're still using weakly typed dynamic languages for example. TypeScript is a decent compromise for me at the moment despite being a fan of actual functional languages.
