I saw a milk that claims to be just that on the shelves. Incredibly expensive and (from what I hear) nowhere near the same taste.
The problem is that animals and plants do "what they do" with incredible efficiency. If you want to do exactly what some evolved thing does best, you probably cannot come close to matching it with technology. A century of aircraft design and planes are not in the same league as birds regarding flight efficiency.
If animal-free milk goes the path that animal-free meat is, they may well be reaching the upper bounds of efficiency already, nowhere near close enough to replace natural animal and dairy.
Which is a bit of a shame (as a meat-eater). I think having outside competition that could truly stand on its own would help reduce the corruption of big ag.
Not necessarily true - evolution (and simulating evolution) is great at finding local maxima/minima, but not as great at moving out of those in the case where the local min/max is not the global min/max. So, for example, birds might not be the optimal way to do flight efficiency, but between birds and optimal flight efficiency if there's a region of worse flight efficiency of any real size (more than you could vault in a couple generations of lucky mutations) then evolution will never find it because the intermediate steps to get there will be selected against too heavily to jump the gap.
I don't think I entirely disagree with you. I was generalizing the real phenomenon that we are unable to engineer competing mechanisms to those found in the wild.
That said, "region of worse efficiency" tends to happen all the time. The accurate argument would be a "region of untenable inefficiency". A legless bird that evolved the ability to fly its entire life from hatching to death is an unlikely evolution. Not coincidentally, finding ways to keep something up in the air longer-term than birds do is something our engineering is capable of.
