That’s only 75 years away, same time since the first work on developing orbital rockets.

But by 2500 sure. And likely by 2500 some form of self sustaining asteroid with propulsion will leave the solar system.

I used to think ince that happens for a few thousand trips, humanity will survive enough that our descendants will last billions of years. Not the same biology, certainly not a single culture, but once the technology exists nothing can stop the spread.

Then I read about the “light cage” concept.
