What's new is that this isn't some back page idea and artist's rendering, it has a motivated person with money behind it, and if this particular motivated person doesn't do it, others will...eventually. The technology will be there.
"Someone will do it eventually" isn't news either. Musk has been making public statements about his Mars idea for several years now and it has made headlines every single time.
As for the quote, he follows up on his quote on twitter and I have seen it repeated on other media pages on my phone
So a twitter comment gets reposted by other twitter users and that makes it news?
Are you powers of critical thinking really that degraded?
