I'm rather bearish on Tesla for various reasons. I also believe current stock prices for Tesla and Amazon are mainly driven by general uncertainty and too much liquid cash with nowhere to go.

That being said, vertical farming doesn't realy solve any problems, food nd water are distribution and not availability problems. None of which are solved by vertical farming. Obviously that doesn't prevent people from raising a shit load of VC money. If anything, the wetern world is producing too much food, incl. meat, in hyper industrialized farms already.
