Too busy coding? Reading about something for _your_ career? In service of _your_ family? Trying to get ahead? Yeah, I get it. But tell me: isn't thinking long-term worth something akin to a few hours a month?
You don't need to be doom-and-gloom about it. Sure, get stuff done. Be in the moment. All good.
Wouldn't it be nice to have some confidence that we're setting up future generations to have the possibility to at least have what we do, if not better?
P.S. FWIW, the morality of valuing future generations is _not_ properly addressed by most moral philosophies.
