It took months to finally solve a data race in Go. No race detector would see anything. Nobody understood what was happening.
It ultimately resulted in a loop counter overflowing, which recomputed the same thing a billion of time (but always the same!). So the visible effect was a request would randomly take 3 min instead of 100ms.
I ended up using perf in production, which indirectly lead me to understand the data race.
I was called in to help the team because of my experience debugging the weirdest things as a platform dev.
Because of this I was exposed to so many races in Go, from my biased point of view, I want Rust everywhere instead.

But I guess I am putting myself out of a job? ;)
