I personally don’t get bored when a tool is “too simple”, but when it forces me to do things by hand that the machine should be able to do. Like manually specializing a generic concept. I didn’t become a programmer out of love for repetitive tasks!
For some people building "complex" things is how they attach sense of accomplishment to programming. If it is not complex, it is just boring or just a toy, hence not worthy of their attention.
Golang is waaay simpler than other languages, as some were designed to be arcane from the start and other became that way over time. So Go's stewards have been doing a good job of enforcing their philosophy so that it doesn't become a bloated monster.
