I have the exact same feeling.
I was using generics extensively in C# particularly. I don't miss them at all after having spent a lot of time working with and understanding Go. I can't help but feel it will just make the language far less attractive in the long run.
Yeah I believe so as well. All languages having the same features would also be a downside. Just make a choice and stand by it. (Like Haskell, they are not pressured into doing things just because Java does so).
