It's just that terraforming will require a lot of materials that will have to be brought over from Earth. And every tonne of materials to Mars requires many tonnes of fuel to launch from Earth.

I don't think it is possible to ever transport enough to make this happen.

Emergent complexity doesn’t really apply to material sciences and organic chemistry in the same way it does for machine learning and digital systems.

I wouldn’t go that far. It was pretty clear a long time ago that humans spending so much time filling the internet with content was going to eventually enable neural networks to pretend to communicate.

The advancements required to arrive at modern LLMs and the tech needed to get humans safely to Mars or live safely on the Moon are orders of magnitude in difference.

Keeping humans alive is hard.
