His actual points in e.g. the Bloomberg interview are considerably more mundane than Dennett's far-future musings. I think it's clear he's trying to get more attention on how dysfunctional/powerless the AI ethics group at Google is to deal with even the real "doctors are men nurses are women" sort of ethical issues. (In particular pay attention to how he frames his question to Page and Brin about public involvement.)

I would say it's been at least a moderate success so far, though I don't see it having much staying power. But then neither did the factual accounts of Google firing ethicists who went against the bottom line, so it wasn't really a bad idea.
