Why do people care about the future?

Are they just NPCs or do most people really think they'll live on after death to observe the planet's future? Maybe I'm autistic, but I just can't see why the future, in general, should matter to me or anybody else alive.

But even on this board I see people posting "we should do this or that to improve things in the future" and I'm like "whatever fag" but others actually engage in the conversation as if it matters. What's going on? Can anybody here who cares about the future explain their reasoning?

Fresh NPC texts:
NPC:Why should i vote? My influence is insignificant anyway.
NPC:Why should i bother about climate change? It will occur or not occur regardless of my actions.
NPC:Why should i care about economy? its not like i can influence it anyway.
NPC:Why should i care about philosophy? its not like i can benefit from it.
NPC:I only care about eating, sex, shitting and sleeping. Anything that doesn't contribute to these activities isn't relevant to me.
