> I found this to be disappointing. More concerned about their brand image than trying to push robotics research forward.

This is a director of communications we are talking about. Literally the beginning, middle, and end of her job description is "Consider our brand image." If she sounds overly concerned about Google X's brand image, that's because it's her job. Google pays her so that the rest of their employees don't have to be so concerned.

Basically every company on the planet with more than 20 people in it has someone making strategic decisions like this. The only difference here is we have a whistleblower reporting what she says internally. There's just about zero to learn about Google's priorities from her priorities, except that none of her immediate superiors is banging the drum for a PR battle over DoD robots.
