i've been over this a few times before; i understand that i'm an omnivore, that this is necessary, but if you look at the animals that we choose to eat...

like, go hang out with a pig some time. these are intuitive, playful creatures that are considerably more intelligent than the animals we keep as pets, cats and dogs. they have individual personalities that you learn when you rear them for slaughter, will respond to names if you give one to them and can even be effectively toilet trained. they seem far too intelligent to be raised in cages for the purposes of consumption.

humans and pigs share some weird similarities as well, like brain structure and skin composition. i've even wondered if pigs may be currently phylogenetically miscategorized as ruminants when they're really descendants of a horrid lost human culture that enslaved and converted a conquered tribe into livestock; the dna may suggest otherwise, but one wonders how powerful a role the environment can play in convergence, via epigenetic expression. hey, humans can grow tails and horns; i'm sure we have the code to grow hooves, too. some back-crossing with the right mutation, and you'd get hooved homo sapiens in no time.

i've never lived on a farm myself, but i've heard from multiple people that there's an almost traumatic rite of passage involved with coming to terms with the fact that the animal friend that you've been playing with in the yard for the last two years is going away because your family is going to eat it. that's a very difficult memory that multiple people i've met have, which demonstrates the point - you feel empathy for the animal, because you've experienced it's cognition.

these issues just don't exist with a species like crickets, who have primitive neuron-like structures but do not technically have brains. it's hard to understand what the signals they experience are like, but we can state confidently that they don't have personalities, that they don't respond to names and that they have no meaningful cognition or intelligence. i wouldn't view raising and eating crickets that differently than i view plant-based agriculture; the best way to do it is probably even in a greenhouse.
