Now convince me, and I want to be convinced, of the reason to build this project without bringing up selfishness or selflessness. If I am a human living here, right now, why fucking bother?

I have no children to think of and that also counts as selfishness if that's the whole reason.

Edit: the reason for selfishness not being brought up is because there's zero chance I see the fruition of this project in my lifetime, which as far as I can tell is all we get, and selflessness is because of the same reason.
