After having written probably over 100k lines of Go code, my impression is that Go is simple, but not easy. The language has very few features to learn, but that results in a lot of boilerplate code and there are more than a few footguns burried in the language itself. (My favorite [1])
I find it very hard to write expressive, easy to read code and more often than not I see people using massive switch-case statements and other, hard to maintain patterns instead of abstracting away things because it's so painful to create abstractions. (The Terraform/OpenTofu codebase is absolutely guilty of this btw, there is a reason why it's over 300k lines of code. There is a lot of procedural code in there with plenty of hidden global scope, so getting anything implemented that touches multiple parts typically requires a lot of contortions.)
It's not a bad language by any stretch, but there are things it is good at and things it is not really suited for.
