This is a pretty odd outlook.

As trajectories go, currently habitable places will become uninhabitable within the lifetime of people you know. And that process isn't nice. Becoming uninhabitable means a series of natural disasters (and clean water pressures) that force people to migrate. Mass migration means global turmoil as people scramble to get safe. And many will die along the way. That's already started.

The planet will physically be here but its habitability matters too. I don't really care about what comes after humans, as long as it doesn't come now and kill me and mine.

If your only argument is "life, uhh, finds a way", that's great. Thank you for your contribution. Now find us a way to relocate a billion people in the next three decades.
