i have been writing Go exclusively for 5+ years and to this day i use generics only in a dedicated library that works with arrays(slices in Go world) and provides basic functionality like pop, push, shift, reverse, filter and so on.

Other than that, generics have not really solved an actual problem for me in the real world. Nice to have, but too mush fuss about nothing relevant.

My most common use of generics is when testing — check out my library for typesafe test comparisons. I find it really useful because I like having readable helpers for asserting in tests, but I also want compiler errors if I refactor things.
