I don't believe that for a second. Even just going from Python to Go drops my productivity by maybe about 50%. Rust? Forget it.

Sure, if you have a project that demands correctness and high performance that requires tricky concurrency to achieve, something like Rust may make sense. Not for your run-of-the-mill programs though.

Hey, going from Rust to Go drops my productivity by maybe about 50% :)

But more seriously, yeah, Rust doesn't make sense for trivial programs. But these days, I write Python for a living, and it doesn't take long to stumble upon bugs that Rust would have trivially detected from within the comfort from my IDE.
