My objection against imitation meat is the same I have against sugary breakfast cereals. They make people believe that they are doing something healthy but in reality they are eating highly processed food that has purely been created for taste and not for nutrition.
Would you be willing to elaborate on the culture change point? Do you think that too few people are concerned about animal welfare to choose the impossible burger over ground beef even if it's competitive price-wise?
So far the Impossible Burger is very expensive and even if it were cheaper it's still not good enough make most people move over from beef. It's a cute novelty item and should be treated as such. On the other hand if lab grown meat ever becomes viable that would be a real game changer in my view.
