It's not a matter of fear. As you say, you can feed a cow damn near anything. It's a living system that takes many inputs and filters them to create a single output of varying qualities. Obviously garbage in, garbage out. But lab grown meat has to be fed a very specific input, and it doesn't have all those other filtration systems. It requires a lot of other non-evolved materials and chemicals, so the output can vary much more.

I'm not afraid of corporations. I'm aware of them and how they operate. They work great for some things. Food is not one of those things, just like healthcare. And when they grow to a certain size they take on very different characteristics because they have to address much larger, less targeted consumer bases.
