"I would have liked to see him address issues like the likely major food shortage (technology will probably not solve this)" We grow so much food it is absurd.

"I would have liked to see him address issues like the likely major food shortage (technology will probably not solve this)" We grow so much food it is absurd. In the 1940's the average yield for corn was 40-50 bushels/acre. Today it is 180, almost all of that increase is simply from better statistics used in breeding practices, an Ag companies have barely scratched the surface when it comes to using genetics to improve yields. If there is a food crisis, it won't be the lack of food that is the problem, it will be politicians and despots at the root of the problem.
