My belief is that Mars will be colonized for ideological reasons, not for profit. A Mars colony won't be profitable. But it will be colonized, mostly for prestige, and also because of overcrowding & pollution, which will become bigger issues in the coming decades.
I say it will not be colonized based on problems of cosmic radiation, not because of lack of ambition or funds.
But why did you invest on those grounds? Is profit not your goal here?
But why? We’ve not colonised either of the poles of our own planet in any real way out of a sense of prestige. Heck there’s huge areas in Canada and Russia uninhabited and these are all a dream to live in compared to Mars.
Turns out the real overpopulation is in places people want to live.
