While I see people worry about the nutrient content in the resulting food, I wonder more about the nutrient content of the soil after a few years of such products. While we fertilize the soil, the mention of "longer and deeper roots" means that such plants will take out more from the ground, making ground less usable for future farming. Basically, as others have said, there is an evolutionary reason plants do not naturally grow this big (they'd kill themselves off in a few generations).
Sure, rotation of cultures is already common in farming, but this implies we'd move further away from organic farming rather than closer to it with the need to re-fertilize the soil to an even bigger extent (and deeper).
Or, it would make us move to other currently unexploited land, thus worsening the global situation we are in.
Basically, there is a potential in this, but I was never under the impression that any part of human population is starving because of us being unable to produce enough food (rather, it's waste and inequality, to name the likely top two).
