Perhaps we are talking at cross purposes, but I know that I was discussing actual vat grown meat, and I strongly believe that is what patio11 was referring to.
Sorry, I think the point I'm making is: "I don't know if you're talking about future-protein or not, but if what you're saying is, 'all progress in meat production sounds good to me, so bring on the cheap Tyson chicken breasts!', yeah, don't do that."
What you do with mycoprotein and cultured meat is between you and your deity. I have no opinions about it. I'm also fine with you consuming all your meals in tablet or milkshake form. Just leave the chickens alone!
It is not yet commercially available, but it is under serious research: http://en.wikipedia.org/wiki/In_vitro_meat has a good summary of the current situation and http://www.newsdesk.umd.edu/scitech/release.cfm?ArticleID=10... has a good laymen's summary of a recent technical paper on its commercial feasability.
