In my ideal system, Peter Singer's opinions concerning ethics will be as important as any other persons, while all to be reviewed by scientists who understand data. Ethics is normal, many people have ethics, but they don't consider themselves "academic philosophers", unless a vast majority of the world are "philosophers", and that's the problem with philosophy. Then just normal ethics.
Altruism is a social science term anyway, in the context of science that is, as studied in the sciences, obviously originated from philosophy, though the term in philosophy is made obsolete.

Sure, the biologies definitely seem significantly weaker as a science, but they merge much, much quicker than philosophy, philosophy never merges.
As Peter has a TED talk on altruism.
