Would you ever live on Mars, if you had the opportunity (pun intended)? I absolutely would, provided it had been proven “safe enough” — that is, I wouldn’t want to be one of the first. But imagine it! Terraforming a brand new world! Becoming a extraterrestrial civilisation!
My fear is that I won’t get the choice, but on the off-chance that I ever achieve immortality, I’d certainly look to moving off-world in a century or two. This is the future I dream of!
