That's crazy fantasy extrapolation, almost too absurd to address, but I will anyway since you asked :)
There are 1492 CVs on StackOverflow right now, and maybe 9,000,000 programmers in the world. Even if we're monumentally successful we're still going to be only a tiny fraction of the hiring of programmers that goes on in the world... a TINY fraction.
I should also add that in the bizarre scenario that StackOverflow actually became a common way of getting programming jobs, it would be a metric ton better than the current system of Monster and Dice and emailing around Word resumes which are scanned in by stupid software that looks at keywords.
I think this post is on the money. You have to bear in mind that right now the "gatekeepers" you're referring to are mostly completely non-technical HR people who might as well be using an Ouija board for all their proclivity finding good programmers. One can argue the merits and demerits of judging someone based on their Stack Overflow participation, but it can't be worse than the current reality.
