I stopped eating meat after being profoundly moved by an article in The Atlantic about nonhuman species having consciousness (“A Journey Into the Animal Mind,” by Ross Andersen). Meat grown in a lab is, so far as I can tell, ethical and humane. It can be produced in a more sanitary environment and saves animals and meat-production workers from the horror of meat slaughter. That is likely to encourage skeptics to try it. Given the choice between cruelty and kindness, I believe most humans will choose kindness.

My spidey senses are telling me this is much ado about nothing. I doubt that the human population of Earth can be supported by lab-grown meat. If it tastes like chicken and costs a similar price, yes, I would eat it. But generally, I think putting our food in the hands of engineers, chemists, and industrialists is a bad, if unavoidable, plan.
