I'm particularly interested in vat grown meat.
As a consumer, I do care about the footprint of my meat based protein, although I don't want to give up eating meat.
As a chef, if they can get marbling in, I'm excited for the different styles we could create.
Note: a plant based reactor (sorry I couldn't remember the term, the seed for the meat to grow with), has been mentioned a few times as becoming close to ready, which would bring the costs down a lot.
