Terraforming other planets would be astronomically more challenging than fixing our own planet and we don’t seem to be able to get our shit together to do that. Even if we are capable of terraforming other planets, it would take many centuries at minimum. O’Neal cylinders are far more likely to work once we start industrializing the moon.

Launch Billionaires into deep space without supplies

We should be exploring both options, exploration can often lead to unexpected discoveries and technological advancement.

D) Move manufacturing and other dirty processes off planet and live here.

Space colonies. That way they can be dropped to earth to start colony independence wars.

Fix our own planet first

Ringworld.

We should stay fucking put until we figure out how to end greed and racism once and for all

All of the above. But start with cleaning up this planet. Build better / more sustainable and more diverse communities and energy production. Build arcologies in the arctic, deserts, oceans. Those are good “practice” for building the same off planet.

Why not both?

I’m guessing B will happen first, just because we have so much more control of the environment, but we’re still so far away from either one… Maybe I’ll get to see the early stages sometime in my life.

Both! All three!

Actually, both.

Genetically modify ourselves so that we can live both in zero gravity (and maybe survive short exposure to vacuum) and on other planets.

How to survive in space: Develop ways to survive in space only first. Once you manage that all the other problems are trivial compared and you don’t have a single point of failure (aka our planet) anymore. Isn’t that obvious?
