The (productive) point of the ethical AI team is to have internal people to consult when launching an AI product. Embedding ethical AI people on teams makes about as much sense as embedding legal counsel. Their services won't be used on a single team nearly enough to justify their inclusion.

Of course, it can be window dressing if the company doesn't actually have product teams care. Just like a CDO position. But you can't patch over a company culture problem with a re-org.
