I see a lot of downvoting here of posts that express very reasonable concerns about privacy if Google is actually using private emails for this AI. That Google is engaging in this behavior is indeed speculation, as far as I know. However, Google employees/allies have to realize that attempts to suppress debate on this issue can only backfire on them. Indeed, the fact that they don't have explicit policy on this (correct me if I'm wrong) is one of the reasons researchers are speculating. It may well be that most people would agree with and/or permit Google to use their data in this way, but people should be given the opportunity to debate it in a reasonable fashion, else it looks like it was forced down their throats. And that's no good for anyone.
