Every Go program written using interface{} to provide psuedo-generics was known to be "wrong" at the time it was written, unfortunately the "right" way wasn't a part of the language so people put up with it. I don't believe that generics are going to radically shift any facet of Go programming and I predict that a year from now they'll be just another feature of the language. If somebody's refactoring some area of code that heavily uses interface{} or code generation maybe they'll considered rewriting parts, but interface{} and code generation are not deprecated or made obsolete by generics.
