This is why I'm not hopeful that lab grown meat will be transformational. We already have a handful of sustainable, widely available, and affordable cow milk alternatives right now and people aren't switching over in droves. Getting people to change their habits is hard without a huge incentive. I can't see how lab grown meat is going to be substantially cheaper (soy/rice/oat milk is more expensive than cow milk in the UK still) or much better tasting to make people switch.
I see people saying things like "I'm sure to switch when it's cheaper and tastes the same or better" but I'm not sure how we'll avoid global warming when people aren't willing to really change anything (vs only willing to switch to identical alternatives).
