Google cannot sell advertising based on my eyeballs if I won't use Google Search, block ads, avoid Google Maps, and download video via yt-download vs. watching it on the far-less-convenient YouTube website or application.
Google have lost me to search, and several other products, for precisely this reason. I don't know the segment of the population I represent, but it is a segment.
A US Department of Commerce survey release this past week reveals that 20% of the population consciously avoids online activities already due to privacy and surveillance concerns. This isn't fully attributable to concerns over Google (and that almost certainly poses a subset of those dissuaded), but it is a surprisingly large effect of privacy concerns.
The trust factor you mention is a huge one. Cognizability is a wonderful word I've run across recently (from William Stanley Jevons' discussion of money). It refers to the ability to instantly and unambiguously recognise a characteristic or trait. Electronic devices lack cognizability of privacy.
Glass didn't do so well as I recall.

"Nearly one in two Internet users say privacy and security concerns have now stopped them from doing basic things online — such as posting to social networks, expressing opinions in forums or even buying things from websites, according to a new government survey released Friday.
This chilling effect, pulled out of a survey of 41,000 U.S. households who use the Internet, show the insecurity of the Web is beginning to have consequences that stretch beyond the direct fall-out of an individual losing personal data in breach. The research suggests some consumers are reaching a tipping point where they feel they can no longer trust using the Internet for everyday activities."

Google's entire business model and value as a company revolves around their ability to maximize the accuracy of their consumer profiles. They have no incentive to do anything other than maximally invade privacy. A device like this from them is even creepier than the Amazon Echo. While it's not released yet, I don't see a disable microphone switch on it either. At least the Echo has that-- though I imagine most users would forget to use it.
The defenders will say "but it only listens when it hears the keyword!" What assurance do I have of this? How secure is this device? Is the keyword recognition performed locally or remotely? What is the definition of "listen?" I'm guessing that like glass the privacy policy will allow them to collect everything.
