We share enough mechanisms across genetics, proteins and even our immune systems and that research is capable of asking meaningful questions that matter to us, and frequently has paid off. That's not to justify the ethics of it but I think it's beyond question that research iN mIcE has been an important research platform for things like immunology and lead to nobel prizes. Research writ large is a vast cumulative program of small iterations that are, individually, of provisional significance, and the categorical dismissal of it as not producing instant one-shot cures is at least as bad a misunderstanding of science as overhyped articles are.
