I have a lot of mixed feelings about developments like this. On one hand, I'll tell people that food for me is about quality and flavor. I'm not opposed to pink slime for what it is, but because it just makes for a poor result. I'm in favor of this on a sustainability level, but very opposed on a quality level—not consistency and reliable textures and taste, but that sort of unquantifiable property that things exude…
Pound for Pound, I could still see an engineered meat cube having better texture than tofu. Even if this was just used for ground beef substitute, it would probably be fine.

I, for one, wouldn't mind trying it out, but I have serious doubts it would approach the quality of real meat grilled burger anytime soon. And I understand that there are places where people are starving and such technologies can save lives, but realistically being the part of the lucky billion that is not under the threat of starvation I would always prefer the real thing if it's available.
