Absolutely, assuming it's roughly on par with real meat in terms of cost and quality.
It's really kind of crazy that we grow all this food to feed a whole animal, when we only want part of the animal. Plus there's the whole ethical question; I tend to not get too hung up about it, but given the choice between meat where an animal was raised in a feedlot and killed vs meat that was grown, I'll choose the latter.
Realistically, I imagine it will be a little while before they can adequately replace a t-bone steak, but I can't seeing it being too hard to replace the meat in any processed or semi-processed meat product. So we'll probably be eating this as chicken fingers first, then as ground beef. Maybe someday they'll figure out how to fully replicate all meats. Then it could conceivably be better than a natural t-bone steak. Perfectly marbled meat with no gristle? Yes please!
