>If you are an employee of a tech company, you use whatever language your employer is using, and you don't get a choice in the matter I've been an employee at many tech companies, and I have always had a choice in the matter. But even if your statement were true, that does not support the idea that languages don't matter. Prisoners are not given a choice of food, does that mean choice of food doesn't matter? You've just repeated your previous red herring. Trying to redirect the focus away from the subject does not make it "case closed". Nothing about startups and picking clients has anything to do with the question of whether or not languages matter.
