From witnessing so many HN flamefests, between Go and Rust, it seems there are people who are genuinely more productive with Go than Rust, and vice versa. Not saying people usually lie when they claim to be more productive with one, but rather that their judgement is very subjective and not scientific. I do wish Go didn't have the data race bugs, though. It greatly weakens Go's "fearless concurrency" selling point for me. To me, Rust doesn't always make concurrency "fearless" in terms of complexity, but at least I'm not fearing actual memory safety bugs in a random library. There's unsafe, but I think the design tradeoff there is quite reasonable and workable.
