food from air water and solar is widely available and tastes good.
You have never been to sub/Saharan Africa or rural India. There are plenty of places where food is not plentiful and the soil it’s terrible or lack of water , pesticides or fertilizers makes growing crops nearly impossible. Taking the land use and more importantly the quality of land needed to produce complete protein is a huge achievement. The Sahara could feed tens of billions of people with technology like this. Use saltwater as your water supply and the air as your carbon source there is so much sun in the day at less than 3% of its land area would power all 8 billion of us at European middle class levels. That is mathematically impossible with fossil fuels for any period longer than 25 years using every technically recoverable resource not reserve at any price.
The Sahara alone could feed 10+ billion and power them at middle class levels only nuclear power can do the same and it would take 6000+ gigawatt sized units of the fast spectrum type otherwise you burn through all the uranium resources in a couple decades. It’s a human population numbers problem at it’s core.
