More like 9 billion circa 2050, possibly declining slowly thereafter. Current birth rate trends don't support a larger estimate. Unless people decide to start having kids again, and those kids survive at present-day rates, I don't see it. I have little doubt that technology would increase the carrying capacity of the rock to those levels, but I doubt there will be a need.
