The mega-PR blitz surrounding the burger seems almost as "yuck" to me as the idea of eating a burger grown in a lab. Scientists need to interact with the media more and talk directly to the public, but this went way too far to the extreme.
We already have the issue of genetically-modified food. And now when we go grocery shopping, are we going to find another label along with genetically-modified food, gluten-free food, organic food, sugar-free food -- real meat and lab-grown meat? Almost funny, but maybe not!
