What's generic programming? An implementation of overloading for datastructures and function/methods. The compiler is left in charge of going through the code and specifying which types should actually be used.
Go restricts the overloading of function/methods. So we are left with the specification of new datastructures. To be fair, unless in very specific cases, datastructures specifically created to be safe for concurrent use are not too useful. The reason being that their content is not deterministic. It is tied to the scheduler. Write-only datastructures are probably the only interesting case that is interesting. I mean, for instance, concurrent writes to a map while no reads occurs. The only interesting case otherwise would be the concurrent reading/writing of an append only datastructure, but that would probably be a very specific tuning for speed. So the only very interesting datastructures that would be remaining are datastructures that are fast to read from concurrently (maps are quite fast in Go) Or fast to write to concurrently. I wonder which kind of datastructures people may want to write. But I have the impression that what people truly want is being able to overload functions. That's complicated. Multiple dispatch may be slow, perhaps unresolvable.. there are issues on that side. Besides introducing unwarranted implicitness. The appeal of generics is probably a false appeal.
