I like the idea in the abstract, but I doubt I'll see a synthetic meat/milk/coffee substitute that equals the real deal for many years, if ever. I'm more worried about the synthetic stuff becoming just good enough that, with the power of marketing and appealing to one's morals, people switch over but not good enough to be a real replacement.

I’m excited for both. Milk too. You can grow all the proteins you want and skip the ones you don’t, or alter the ratio as desired and have the same product much more efficiently and ethically. Maybe even a better product. The Brave Robot ice cream is grown without lactose for example.
