@Yendor Point is that it's jumping the gun to think we can escape climate change by rocketing to Mars and terraforming the climate there, rather than just concentrating on terraforming Earth back to a liveable environment and THEN worrying about moving elsewhere. If we can't keep Earth inhabitable, we can't make Mars inhabitable.
Just like people who think Large Language Models are genuine AI are completely jumping the gun about what we're capable of coding right now.
