Honestly for me that's almost beside the point, the fundamental challenge with lab grown meat is cost. You need close to sterile conditions, you need a viable, cheap, presumably vegan growth media, you need seriously skilled technicians... and this is all in competition with rearing livestock. You don't need people with PhD's to raise cattle or chickens, you don't need sterile conditions, and the many challenges involved in livestock have been explored by all of humanity for thousands of years. Even more with corporate, large-scale operations, the efficiencies of scale are enormous.
How on Earth anyone thought that lab-grown could compete with that, when price matters so much to people, blows my mind. Sure there are some vegans and some relatively well-off people who might be interested, but that's not a scale that matters.
Then you have to ask about the taste, texture, and nutritional value... none of which appear to be a good match yet.
