I second this - cow based protein and cricket based protein both supply adequate value in an average human diet - why is there such a stigma against one versus the other?
It's cultural of course, but the funny thing is that kinda-insects are already culturally accepted food in the west – but only ones from the sea such as shrimp, crabs, etc.
I had them fried and seasoned/salted iirc, they were surprisingly good little snack. I think it'd take a bit of time for most people to not be squeamish about casually eating them, rather than as a little novelty thing at a food festival.
