Wired covers the Test Tube Meat story. Short version: hamburger in two years, steak in 10 (steak requires better alignment of muscle fibers and the ability to recreate blood vessels running through). Stuff being grown without scaffolds in 1mm sheets, which can then be stacked to create thicker cuts.
The “yuck” factor: “But it’s not natural!” And how natural is it to stuff 10,000 chickens into a metal shed, snip off their beaks and pump them full of antibiotics and hormones? How natural is it for cows to eat corn? (which is pretty much all factory farmed cows eat, much to the detriment of their livers).
This research strikes me as a great leap forward in human consciousness. I hope that one day we’ll view factory farming as a barbarism of the past.
