No one has addressed the real problem inherent in this: our broken agriculture system. When it takes 8 grams of oil energy to produce 1g of food energy and we feed grain to cattle (and antibiotics to keep them healthy on an alien diet), we have got things severely wrong.
Why not printable vegetables first?These would be more palatable than the idea of eating a printed meat.
Or for that matter we should first get habituated to this printed food concept by eating say printed bread or printed biscuits.
Something tells me that a variation on this theme is in our future whether we like the idea or not. Already we have "pink slime" which is meat that's been mechanically chewed off it's host and more or less recreated. We have water and flavoring being injected into meats and who knows what else.
If it is deemed safe for human consumption and is less expensive to produce, it will end ina a store near you.
