Building colonies on the Moon and Mars are important first steps, but I think ‘colonizing’ as a long term survival strategy should be focused on the eventual goal of establishing life in multiple star systems.
And by an unbelievable (bordering on comical) coincidence, the closest star to us is furnished with an earth-sized, tidally-locked planet in the habitable zone.
And that star won’t leave its main sequence for 4 trillion years.
Trillion.
That’s the long-term, off-site backup we should be looking at for our business model.
