I'm pulling out my vegetarian pass to say, without hypocrisy, that Neuralink's animal testing record appears to be pretty horrific.
As for medicines, I’m not sure what to do about that. Where I draw the line in veganism is essentially where I’d die if I don’t eat the animal. If there’s a necessity, I think it makes some sense. Some medicines are a necessity for people. Yet I don’t like the idea of supporting companies which would likely be testing non-essential medicines on animals as well.
The world isn’t really configured for veganism
