It is promising indeed but many things that are promising they still have production limitations. I heard once a vegan saying that if this type of food becomes popular he becomes a meat eater again. I think the no demand is because of the price! I am a non-rich costumer so if you put me in a table a lab meat costing dozens of times more than a a regular meat, I will still go towards the regular meat! If there isn't a way to reduce this cost, is worthless
