Yes, this is exactly where I disagree strongly. Malthus and his imitators have all been horribly wrong. I will concede that there is ultimately a finite amount of stuff in the universe, but looking at any apparent hard limits like you suggest has been a recipe for undue pessimism. For example, I don't think "arable land" is a fixed resource.
Anything seems possible when you don't know what you're talking about. There is no spare agricultural capacity to be had anywhere on this planet and the required inputs are both not something we can replace and dwindling.

I know what I'm talking about! I'm talking about how the food ain't gonna run out. If that makes me stupid, then so be it. I'll be stupid and right.
Where are you expecting all of this bonus food to come from? Mars?
