Abstractions do have costs, no doubt. I just don't see the connection between "Go heavily uses interfaces which force heap allocation in the current implementation" and "1975 programming". How would one go from 1975 to current year? By stopping using abstractions? Isn't that exactly what 1975 programming was to begin with?
