Professionels in the actual field of conducting animal trials and getting medical devices through FDA approval. No one who has ever worked even just as a week as an intern in the field would ever have the blatant disregard for proper procedures they had. It’s just as insane as if Elon had said “just put a dozen or so untested self driving cars in the city center and see if they crash”. Animal testing isn’t something where you go “Oh it’s only an animal so we don’t give a fuck how we treat it”, there are very high bars that you need to stick to. People know that if they work in the field, which is why you need professionals and not just biohackers who don’t care about any established processes and just want to skip them in the spirit of “the ends justify the many animals we carelessly brutalized without any care taken to avoid it”
