I came here to say "can we worry about building programming languages in twenty-four years instead, please?". Someone who has gone through your list is exactly who I want actually building the next generation programming languages. Of course your last question is the best one: > eh, why bother This is absolutely the question you need a deep answer for. You need a problem that is burning you up and whose only solution is a new programming language. This might never happen. If it ever does, you're the person to do it, exactly because of all the ups and downs and half-started ideas you've thrown away. But you're right: the "why bother" stage is not to be ignored. It's the most important one.
