I think it's a really interesting concept, although kinda nonviable at the moment due to economical/production reasons. Wouldn't be surprised if it became the standard in the next couple centuries, though.
There's probably still a major stigma around it about people that think it will never taste as good or afraid of it having too many chemicals to make it similar, and I feel like people kinda miss the point here. As far as I know the idea isn't finding a substitute for meat, it's finding an alternative way of obtaining the meat. Lab meat is meat. Meat is meat. It's not like a vegan burger trying to mimic the contents of meat with other stuff, it's literally meat. It probably has some differences from traditional meat because of differences in the fat/muscle ratio and other stuff like this, but it's literally meat, lol. Once it gets fine tuned it will be literally the same composition as normal meat, the only difference is that it was synthetically made.
If anything I feel like it would be healthier than the traditional meat that we eat nowadays that shoves drugs and artificial hormones down the slaughter stock. Not to mention potentially being able to control diseases better like BSE, taeniosis, bacterial infections, etc.
