Okay, now this one bothers even me. I don't have any problem with using human embryos as throwaways; as far as I'm concerned they're ethically equivalent to rocks as long as no neurons have formed. But I'd be really disturbed by letting neurons form in these embryos on the theory that they're not "really" human because they started out as cows. Human is as human thinks, and a "human" embryo is a matter of human DNA. These embryos aren't human because they don't have brains - not because they're hybrids.
It's not the throwaway part that disturbs me. It's the idea that these transplanted genes are somehow "less" human. While I admire their judo-like self-cancellation of technophobic attitudes, I think they're promoting dangerous prejudices.
