I think pretty much everyone would agree that's bad. However, I don't think we'll ever get to the point where we recognize a machine might be capable of suffering. There is no way of proving anything, biological or not, has a consciousness and the capability to suffer. And with AI being so different from us, I believe most people would simply disregard the idea.
Heck, look at the way we treat animals. A pig's brain is very similar to our own. Nociceptors, the nerve cells responisble for pain in humans, can also be found in most animals, but we don't care. We kill 4 million pigs every day, and 200 million chickens. No mass murder in the history of mankind even gets close to that.
The sad truth is, most people only care about their wellbeing, and that of their friends and family. Even other humans don't matter, as long as they're strangers. Otherwise people wouldn't be hoarding wealth like that, while hundreds of millions of people around the world are starving.
Ah sorry, I kinda started ranting. Yes, I'd care.
