"current systems are too primitive to feel or understand."<p>Is there evidence to suggest that if it can feel or understand, that would actually be an issue?<p>Every day millions of sentient beings are killed for human consumption and millions more wait in torturous conditions.<p>It would be odd if there was outrage over a bio computer, but not over, say, the practice of using cows and pigs for food, which feel pain, have rich emotional lives, and have the inteligence of at least small children.
