This terraforming Mars argument always sounds a bit “mechanical horse” to me. By the time we’d be able to do this, we would have merged our “survival machine” human body with technology and would not require the incubator of earth’s environment to survive. Feels more likely that in a century or two we’d have essentially immortal carbon nanotube exoskeletons wrapped around human brains going wherever the hell they want across the solar system and beyond.
