Futurology

A field costs next to nothing to use. Setting up and maintaining a vertical farming setup already is not competitive. Add another layer of complexity with DNA engineering etc. and how exactly is it suddenly supposed to be competitive?

The nonsense 94 % number can go right down the toilet. If I plant my stuff on the side of a building it needs no space at all. If I put the vertical farming flat on the ground it's a bit less. If I put it in the highest possible building or underground it's essentially zero again. The number is useless because it is arbitrary.
