It’s not about technology, it’s about incentives. Unless the cost of settling and living in Mars becomes extremely low there will be no rational reason to invest into any large scale Martian colony.
Why don’t you move to Antarctica? We have the technology that would allow use to settle millions of people there. We don’t, because it’s cold, there is nothing to do there and there much nicer places to live further north. In the case for Mars multiply all of that including the cost by (idk) 1000? 10000 times?

I don’t see the analogy here at all. Yes Columbus took a risk, he did that because he and his investor expected to make a lot of money just like the Portuguese going around Africa did. How is that relevant?
Europeans colonized America because it was green, warm, full of resources and otherwise about as nice as Europe (just with a lot less people due to various reason). OTH nobody colonized Antarctica or the northern half of Greenland etc. due to obvious reasons..
I'd agree about the economics; when Musk suggests people getting out a loan to make the trip, what bank would grant that loan? How would they collect on it? What's Mars going to sell to Earth, which it needs to in order for a bank on Earth to accept a repayment? When he says "People will want to create the first pizza joint [on Mars], the first iron ore factory", that makes me cringe — the former because it's the kind of low-income role that needs food stamps in California (or at least, I know someone, n=1, where that was the case) and can't possibly afford that trip even with his price optimism, and the latter because if that's not already fully automated before you arrive, you probably can't build the colony in the first place.
I do however expect that there's enough psychological draw from "the final frontier" to get a million people spending $100k USD for the trip. Can he get that cheap? No idea.

Because what he was actually aiming for wasn't possible, he just got lucky there was a (just about possible) alternative that he happened to find purely by coincidence.
What I'm expecting, is that we get von Neumann replicators before a Mars colony reaches the current population of Greenland (56k), let alone a million, and also that a lot of people will prefer the Moon instead (the ways in which the Moon is harder are not ones I expect to be important compared to the difficulty of either). But I also expect that some random thing which gets invented specifically as a result of the attempt to colonise Mars to prove really useful in some impossible to predict way.
