Likely yes. If generics are implemented via monomorphization, then you can avoid the overhead of virtual calls necessitated by interfaces.

It is possible that the compiler could become smart enough to devirtualize calls through interfaces.

Pretty sure devirtualization is a whole program optimization in the general case, and I don’t see the Go dev team Pershing that in the next couple of years.

Agreed. But if I didn't mention it, I'm sure someone would have felt obligated to respond with a "well actually..."
