Go will lead to a generation of "stupid" developers writing "stupid" code because they were told you don't need "this or that", then the next generation will rediscover things such as functional programming,generics or type classes. Or Go will evolve to something more complex, like every language do and early adopters will be pissed off things aren't like the "good old times" anymore as they are incapable of using constructs they don't understand.
Go developers already have that "dumb-down" reputation.
