One thing that concerns me about hacking crops to have higher yields is that they may consume more soil nutrients, when we’re already in pretty serious danger of exhausting large patches of arable land. So then we’d need to use a lot more fertilizer, which is already an environmental disaster at its current scale with nitrogen/phosphate runoff. There’s no such thing as a free lunch, unfortunately.
