Of course price dictates a lot maybe certain cities it will catch on more than other, maybe in the East it may become more popular than here in the Canadian mid-west, it is farmed right here, even living in the city it's still pretty close to the source. As it gets more expensive here, more are shifting to buying farmers direct to save on costs rather than seek meat alternatives, the markup from the supermarket alone is insane.
Sure they will grow in popularity but I doubt it will become the dominant market over meat at least not this generation. Convenience cost $$, I see lab grown as a means of convenience and a lot of people are going to have a problem with the concept itself like gmo's and rgbh.
