Even Stephen Hawkin believes the human race will be extinct within 1000 years.. ok, so that’s quite a long time to kill ourselves to death. But he’s not the only one to think that way.
Money can’t buy immortality, it may prolong death, but death is the only outcome. Even advances in science and biometrics will only replace worn out bits. Money or power will never replace spirit, that’s the only thing humans have, and that isn’t strong enough I feel for humans to progress.
There are too many people here on this planet, we’ve been very lucky not have been blasted by an asteroid or radiation. But I think extinction will come from within, not from above. Humans have a propensity to kill or be killed, the flight or fight instinct in some is stronger than in others. We already have humans in places in society willing to be the first to poke the stick, we see it daily. Take away basic human needs and society fails, factions gather and with that we only need a despot or desperate power driven looney to provoke retaliation.
Sadly, we’re doomed to fail, but I’ll be long gone by then..thankfully.
