Not a vegetarian here, but I'm really excited about companies and products in this space. There's a lot of very poor quality meat out there that can easily be substituted by these products for cost, nutrition and environmental reasons. The way I describe the Impossible Burger to friends that haven't tried it is "If I invited you to a BBQ with decent store-brand frozen patties and randomly inserted Impossible patties, you probably wouldn't notice".

I have a general prediction about these products though: I think they'll follow the broad development of art and games. Initially they will work very very hard to produce something that is as close to meat as possible, just like gaming worked very hard at photo-realism for many many years. But once they reach close enough, people will actually get bored and new and more interesting meat-like products, which traditional meat could never produce, much the same way gaming gave up photo-realism and many hit games started taking on more artistic qualities.
