I believe even the language's own designers would agree with that sentiment. There's just generally a lot of things about Go that are great for low-level microservices but not great for 1M+ line of code business applications maintained by large teams.

I can't speak for others, but personally if I'm writing software with complex business logic, I'd want null safety, better error handling, a richer type system, easier testing/mocking... I've also never liked that a panic in one goroutine crashes the whole application (you can recover if it's your own code, sure, but not if it happened in a goroutine launched by some library).
