Fake Meat

We had to wait for the ’90s for it to become more palatable. But now it’s a 3rd generation with new tech and the consumer does not have to sacrifice taste any more: people are just enjoying it because it’s good, not because it’s plant-based - Dan Malek

The trouble with the Internet is that it's replacing masturbation as a leisure activity - Patrick Murray
