Yeah, its incredible the amount of people that seem to believe that colonizing mars is right around the corner, when the most inhospitable places on earth, like Antarctica are many orders of magnitude more habitable (they at least have trivial to access air and water), yet contain to a first order approximation, nobody.
It also has the bonus of not being millions of kilometers away, and hundreds of billions of dollars for a small crew to reach.
It feeds into the dangerous fantasy that once we ruin the earth we can all just go to mars and teraform it.
We can't, not even remotely close, and neither will your grandchildren's grandchildern's grandchildren.
