As a Rust learner (for 1 year already), I can confirm that these are legitimate worries. Learning curve can turn many away, and supply chain can be attacked as well (I haven't met any mentions of security checks of crate updates to prevent them). #2 is, I think, part of #0: when you learn the language you meet a good deal of new terms -- though not acronyms -- they're significant, but you're not yet able to gasp all of them, it takes some time. But I haven't seen outright hostility in the community. BTW, we had a discussion about monads in Rust forum, and I pointed at this same self-referential definition.
