I think you are referencing two different things. Expecting vegitarian meals to be the default wont happen for a long time. People like meat for a lot of reasons.

However, lots of wonderful resturants and chefs are creating vegitarian and vegan food that in no way immitates meat based food.

I also think, though, that if we can create lab grown meat that is identical to meat but doesn't involve suffering or enviornmental harm, that's a win. Most vegans I have polled would eat it, as long as their stomach could handle it.
