The demo prompted a furious reaction, though, from the animal rights organization People for the Ethical Treatment of Animals (PETA) — because it revealed that Neuralink has been testing its experimental brain hardware on pigs.
"PETA challenges Elon Musk to behave like a pioneer and implant the Neuralink chip in his own brain," said PETA president Ingrid Newkirk in a statement. She also accused Musk of "exploiting smart, sensitive pigs who didn't volunteer for surgery" and "should be left out of pie-in-the-sky projects."
Unlike Tesla and SpaceX, Neuralink does wade directly into the culture war over animal testing. You can test rockets and electric cars without animal research subjects, in other words, but only the fringiest people would volunteer for brain surgery to try out an untested medical device.
Musk didn't mince words during the event, speaking highly of the pigs as research subjects precisely because they have higher brain functions that are more comparable to humans than small mammals like mice.
"Pigs are actually quite similar to people," he said during demo. "If we're going to figure out things for people, then pigs are a good choice."
"If the device is lasting in the pig, as it lasted in there for two months and going strong, then that's a good sign the device is robust for people," he added.
At the same time, he did show some affection for the animals, introducing an animal handler and showing off a healthy-looking pig that he said had been implanted with a Neuralink device that was subsequently removed.
But Newkirk wasn't impressed.
"Musk has the brains and ability to use technology, why not wise up to who animals are and show them some respect and try this on himself," she said. "He knew there was going to be a backlash against his use of pigs, and had the nerve to come out with a PR reel in which his lab staff talk about how much they care for the animals he uses."
