Jeff Bezos dismisses idea of a backup plan, says we must protect Earth

I think they are both right. We want earth to be a beautiful "residential district" AND we want a backup plan.

Does Amazon run without backing up its data???

Agreed ... and not that I want to cast aspersions, but I can't help but noticing his space company will play no role in setting up an off planet backup except for maybe providing a rocket engine.

Makes sense to me. In the near term "space as industrial park" sounds more plausible than colonizing mars. Certainly we would want to live on other planets eventually but the economics have to catch up first.

In reality, a "backup plan" for humanity would come down to a few lifeboats for a very few. We wouldn't be saving humanity, just it's DNA.
