Also, it appears humans cannot digest chitin (like we can't digest cellulose) and thats most of the bug's dry weight and they have a horrible taste except for grasshoppers. No, you wont get used to the taste.
Bug farms have to feed the bugs anyway, with waste plant products. Too bad so many users are competing for that waste: Vegetable protein extractors, ethanol producers, biomass power plants, etc. Looks like we are gonna need to clear more rainforest to feed our growing bug industry.
