The automation thing makes a lot of sense for food if you aren't growing in soil. Farming is HARD work but if we could grow more with less water (even vapor!) in drought stricken areas I fail to see the drawbacks.

As someone who dwells in the jungle I love permaculture and I think it is pretty cool but I also like the idea of solving mass starvation on a large scale. I don't see what is done here with permaculture feeding the world any time soon, but I also don't even buy bananas because I'm sick of seeing the infinite banana tree fields
