Generics use the type system to make the compiler check the code for you. It makes the code easier to understand, more correct, and concise if you use them as they were intended. It avoids tedious and error prone duplication of logic. Create ONE efficient debugged implementation and reuse it as much as possible. The crappy workarounds for generics introduce their own complications and issues.

But I know what you mean. I've worked on Scala code for years and seen less mature developers over-engineer things and get way too clever with the type system. Scala is a really practical and powerful industrial language that requires some maturity to use the abstractions sparingly. It's only good for the top 5% of developers.

However, Go doesn't have such a powerful type system. It looks like the Go designers implemented relatively simple generics. You have to draw the line somewhere. If simple Go generics are too confusing and complicated then that developer should probably find another job, as generics are a basic concept in programming. The Go designers are pragmatic people, and they've decided that relatively simple generics will make things easier in mainstream commercial codebases.
