The Earth only developed intelligent life a few million years ago, us (homo sapiens) a few hundred thousand years ago.
We've only been in "technological takeoff" for ~250 years and are already using spaceships and computers to deliver and operate drones on Mars.
Now imagine 250 years + 1,000,000 years.
It is impressive, but there’s no reason to think it will continue on the same trajectory.
Civilizations collapse, do you think we're immune to that now because technology is at some level?
