20 years later, same promises as 20 years ago, now with "vastly increase the probable lifespan of consciousness, as we will no longer have all our eggs, literally and metabolically... on one planet"
Getting into Stefan Molyneux levels of breeder fetish egg fixations, too.
"We will figure it out when we get there. Can't make an omelet without breaking some eggs. Where is your sense of adventure? You think SpaceX didn't already account for that?"
Any competent engineer would have accounted for such a basic and obvious threat to life in space and mars such as radiation. Therefore no further inquiry is required we can just give him the benefit of the doubt.
I even saw a bazinga webcomic that mocked the idea of radiation being a problem by having the "command center" at SpaceX(tm)(r) announce "someone on the internet brought up radiation! We forgot about the radiation, everyone! Stop everything!"
The only thing that didn't make that joke actually real was the stopping everything part.
