You're right, but downvoted because it is much, much harder to do what you're asking. But it's just bad science to ignore or not want to do something because it's harder. Modeling biological or physiological systems is something we do via animal sacrifice as well. My own research uses mice. I think current versions of LLMs could be used for synthesizing the framework of such models, at the very least. It would certainly make for an interesting open source framework, and would be pretty valuable if done right. There are some options already, but they are too specialized and not geared towards systems biology or physiology. Mainly the way I think about it is that a mouse can't reason with you about why you shouldn't do what you do to it. So you, as the more analytically mature being have to make up your own reasons. Is it worth it? That would be a digression for this post.

But more importantly, a lot of bad science is done while wasting away animal life. Regulatory bodies can at least do something to make it less cheap or harder to justify the use of animal models. Or at least ensure a higher standard of expectations for having used animal sacrifice.
