I mean, if we're talking about all those problems, the no-type-annotations issue is rather specific for Python, JS/TS and Ruby.

But in general, I feel like there's somewhat of an old world vs. new world divide, which happened when package registries started accepting libraries from everyone and their cat.

In C, for example, most libraries you'll use will be quite well-documented, but you'll also never hear of the library that Greg's cat started writing for the niche thing that you're trying to do.

Unfortunately, Greg's cat got distracted by a ball of yarn rolling by and then that was more fun than writing documentation.
That's the tradeoff, you get access to more libraries, but you just can't expect all of them to be extremely high-quality...
