Fadeaway,
To think that mammals like cows do not experience pain is about as insane as saying they do not have eyesight despite having functioning eyes, displaying all signs of using eyesight for navigation and sensory understanding, possessing optic nerves, and a complete visual system. It's just a giant: WTF? I really don't want to repeat all the information about the nervous system and pain that I've already gone on about, so I'll just restate: Mammals feel pain. This is a simple fact. They possess all the same neurological components that generate the experience of pain, and display every behavioral sign of it as well. If you want to claim that other mammals don't experience pain, you'll have to go out and do some pretty ground breaking research and disprove pretty much every single thing known about the mammalian nervous system in the process.
And yes, fish feel pain as well. I remember when I was a kid and went fishing with my parents I asked them, "Doesn't the fish feel pain when it gets the hook stuck in its mouth?" and they told me, "Oh no, fish are designed to not feel pain in their mouths so that we can catch them." And I believed them.
Things like "Oh, animals don't feel pain," are lies we as a society tell ourselves, because if we did acknowledge animals feel pain it would make us very uncomfortable with our lifestyles. No one thinks of themselves as a bad person. No one wants to think that every single day they are engaging in the single largest genocide in history, the systematic cruelty of tens of billions of animals every year. If we acknowledged animals feel pain, we would have to look differently at our chicken dinner that had its limbs cut off with zero anesthetic, suffered organ failure and crippled limbs from our genetic modification of its bodies, and then had its throat slit open while it was conscious, and perhaps was even scalded alive in the de-feathering tanks.
I once talked to a worker in the pork industry, who as part of the job rips off the testicles of squealing baby pigs, and he told me with a straight fact, "The piglets don't feel pain, the testicles just fall off." If humans are masters of one thing, it's of rationalizing our behaviors no matter how horrid they are. I told him, "Fall off? Are you joking me? You are ripping off an organ with your hands. You saying if I grab your testicles with pliers and rip them off right now it's a-okay because they'll just fall off, no pain, no problem?" He didn't have a response to that, only looked incredibly uncomfortable.
As a society we have to stop rationalizing atrocity just so we can feel good about ourselves. That applies to every sector of life, not just animals.
But to think that animals don't make choices, that they aren't capable of compassion, love, friendship, and volition, and are only mindless procreating and eating machines, only shows an ignorance of animals. In our societies we are so detached from animals except cats and dogs that it's not surprising, but if anyone spends time with animals, and gets to know them, it's impossible to say they don't experience all of those things, and are just mindless bags of flesh.
People see clips of animals hunting each other in documentaries and think that that's all there is to animals: mindless instinct to survive. But that's as narrow minded as watching a clip of humans murdering one another and extrapolating that human beings are mindless killing machines. With our own species we are surrounded by all the different facets of humanity on a daily basis, so we don't have a single narrative in our mind for what "human" means. But for animals we have such limited exposure to them that we do form very biased, ignorant views of them based upon fragments of information. We do this to our own species too, creating stereotypes and prejudices towards people groups we don't have much exposure to, such as Americans who have never been to Africa thinking of Africa as just poverty, disease, and death, when in reality "Africa" is a place of infinite narratives, not just our media stereotypes. So it's no surprise that we do this tenfold towards other species, when we do it constantly to our own.

Should we be horrified if insects have legs cut off with no anesthesia (assuming such a feat is possible) in an experiment? What about mice or rats? As was mentioned earlier in the thread, are we just showing favoritism to mammals cause we are mammals? Put another way, is it simply because animals have a nociceptor response like ours that they should be given compassion? Or is there some other quality?
As a thought experiment..
I honestly don't know much about the nervous systems and pain experience of insects. Where the line is drawn is up to the individual, and some people do feel fine eating seafood that doesn't have central nervous systems, or has very rudimentary ones, yet would never in their dreams think of eating a cow or pig. Favoritism towards mammals tends to be shown simply because we know the most about how the mammalian brain works, and can relate more to their experiences of pain and suffering. But yes, animals like rats and fish experience pain as well, and I find cutting off their limbs with no anesthetic to be just as morally sick as cutting off the limbs of a mammal.
As for the AI argument, just watch Spielberg's "AI"

The ethical arguments of AI are very interesting, and I love sci-fi, but bringing them into this argument is as silly to me as people who are anti-gay using that argument, "Well if we let gays get married then where does it stop? we'll have to let people marry dogs, and it'll be a giant landslide effect." It does nothing but distract from the real issue at hand by bringing up extreme hypotheticals. The inhumane slaughter of tens of billions of animals is going on this very instant, whereas no genocide against AI is, so frankly I don't think there's any merit to discussing the comparison.
