Of course we need more languages. We need to continue evolving languages until we get better and better ones. When languages stop improving so significantly from generation to generation then we can start settling down into a smaller number of languages. We still haven't figured out the best tradeoffs between dynamism and type safety. And we definitely haven't sorted out the best set of features for memory management and error handling. And after that there are a lot of even bigger fish to fry.
