- Generics has seen quick adoption.
- Fuzzing is new to most Go developers.
- Third-party dependencies are a top security concern.
- We can do better when announcing new functionality.
- Error handling remains a challenge.
Otherwise I really like using it, and would replace it everywhere python is used.
I normally don't hold back against corporate projects and especially Google's list of forgotten or mismanaged ones. However, I've always felt Go has been doing well, compared to other languages. Older languages painted themselves into a corner (Python, C++) and newer ones (no names mentioned) already struggle with painful design-by-commitee compromises and identity crises.
Every year or so I check in to see what's new in Go, and I'm mostly pleasantly surprised. They're addressing long standing feature requests, add meaningfully to the std lib, and tools get a lot of love as well. Sure, things are incredibly slow sometimes, but long term stability of a global and mature language is one of the hardest things to maintain and grow safely. They also don't leave users hanging with gaping ecosystem holes anymore (anyone remember the pre-go mod days and GOPATH hell?), when other languages throw their hands up and say "HTTP isn't our responsibility, that's a 3p issue" or "it's not our fault people misuse our language features, it's devs that are stupid".
