"Blub" as a concept isn't really useful anymore. I've seen people attacked as "blub programmers" for criticizing Go for its lack of features. At worst it's a personal attack ("you are a short-sighted programmer"), at best it's kind of supercilious ("language X is great, it's just over your head").

I think "blub" is just another example of "you don't know what you don't know", which is always going to be relevant. And not everyone have tried, or intend on trying, obscure/sophisticated/mind-bending programming languages. And that's fine, since we all have different interests (as long as we don't try and pretend that we are very knowledgeable about something which we don't really have an interest in pursuing).

But to call someone a "blub programmer" does come off as quite rude.
