It is. Show me a single individual with a time horizon that exceeds their own life or that of their children. That means you have to be early 20's or so today (or late teens) and that you are aware enough and capable enough to act on something that is not an immediate concern for decades. I don't see that happening, even if a handful of such individuals exist it won't be enough to make a difference, and that's before we get into cultural differences which undo your efforts because others are going full steam ahead anyway and probably in much larger numbers.

I mean we are 50 years away from a lot of existential risk and the average guy does not give a fuck.
