Earth too shall pass

The Highest Heaven
(Illustrated by Gustave Dore)

Scientists are predicting that Earth will no longer be habitable in about a billion years.  Those who are counting upon AI for physical immortality will then have to flee to God knows where.

And that is the point. Although some conceive immortality to be Groundhog Day for eternity, others prefer a heavenly future. Not the kind of heaven that can be accessed with a spacecraft, but the kind of Heaven that does not require a flesh-and-blood appendage.

Although a billion years might seem ample for figuring out space-based logistics, consciousness would need to keep pace with intellect.  Otherwise, as Carl Sagan warned, it might be best for humans to remain quarantined on Earth until ready for another realm of Being.
