What comes most to mind is the impossibility of flight and the mortal peril of traveling at speeds above 60 mph. I.e., "never" is a lot longer than hyperbole allows for; and, it's easy to poke holes in a selected straw-person, a lot harder to anticipate the manners in which someone might change some of your axioms out from under you. One off the cuff example: actual-whey-protein non-animal ice cream is now available down the street from me. Is it "vat milk"? Well, no; it's a novel solution that marries the actual protein in cow milk, with fats from vegetable sources. They didn't violate thermodynamics to produce an interesting middle ground between cow-milk and plant milks (oat, almond, soy, coconut, whatever). Similarly, it's a lot easier to tsk tsk about some arbitrary idea of what cultured meat is, than to anticipate the ways in which it might be grown which have nothing to do with your tidy model. As an aside, I'm interested to look in who is funding David there. The American industrial farm meat industry has a LOT to lose if we get vat-bacon. Certainly enough to fund some opposition research water-muddying, eh?
