Super-intelligent folks are the target of google's hiring.

I suspect these types of people can work anywhere, they get to pick and choose.

If they can pick and choose, they will have other motivations, like being able to make a difference, and not blindly create a dystopia for everyone on the planet.

So... having an Ethical AI group lets people join google, look themselves in the mirror every day, and know their employer is trying to do things right.

I don't know what the reality is of an Ethical AI group. But having a good one that works might make the difference hiring exceptional people.
