434 points on HN argue that Async Rust is still a glorified MVP. I replicated every concrete criticism against reproducible example code: executor leaks, cancellation safety, Pin hell. My conclusion is more uncomfortable than the original post.
648 points on HN about bugs Rust doesn't prevent. I took the list, ran it against reproducible production-style examples, and found exactly what they promised wouldn't be there. Rust gives you memory safety, not logic safety — and that difference matters more than the community admits.
I had Rust code in production with mutexes. It deadlocked at 2am. Zero compiler warnings. When Surelock hit Hacker News with 214 points, I opened the repo and finally understood why the borrow checker gives you false confidence about concurrency.
33 years with computers and I only just understood what happens between typing `./my-program` and the code actually running. ELF, dynamic linking, ld-linux — the black hole I kept dodging.
