Bro has discovered biotechnology. I think this idea will die because people won't adopt it. If people knew how most drugs were produced there would probably be a bunch of people that didn't want them anymore. You can already see this in small things like microbial rennet that is equal to animal rennet in all relevant properties and yet (at least in Europe) you still see a lot of animal rennet and at least from my observation the percentage of animal rennet in higher quality cheese (the ones that aren't pre packaged but still available in supermarkets) has risen in the past years
