I'm not sure why you're being downvoted for this. It's one of my concerns, as well. The idea of inviting Google into my text messages, which is a far more private and unfiltered place than my Google searches in a browser, makes me a bit uneasy. The parent's notice that it wasn't transmitting everything one types is helpful. I send a lot of GIFs, so this would only make my workflow faster, but I don't want to have everything I do with a keyboard tied to my Google account because I'm using a keyboard.

It makes me a bit sad to recognize that my first thoughts and reactions to many Google announcements these days—even silly and playful ones—is to start ticking off and formulating potential vectors for identifying and collecting things about me that can be turned into juicy bits for advertisers.
