 2.2.18  6:09 am why would colonizing mars be stupid?
one reason i used to think it's stupid is because mars is so insanely different from earth, if we go there we're probably going to instantly hate it and it would be psychologically traumatic on a very deep level. but Elon Musk makes some great points which are 1. we can change it, but more importantly 2. it's good practice anyway because we need to have the capability to be multi-planetary in the long run, because sooner or later something will happen to this planet
