Works up until the earth becomes uninhabitable in 600M years, before then humans are going to need to find and colonize a different planet.

If mankind exists in 1000 years time and hasn’t regressed then we’ll be able to build fusion powered self sustaining asteroids. Those can be used as airships to colonise every system in the Milky Way in a few million years.
600M years is enough time for Earth to try two or three attempts at intelegence, with full blown fossil fuel replenishment cycles. It won’t be humans - whether we leave for the stars tomorrow or blow ourselves to bits we’ll have evolved to something unrecognisable by then, but there’s very few things which could end life on earth in the next 200 million years (mainly very large out of system asteroids/rogue planets)
No rush then, modern humans aren't even 1m years old...
