I don't mind Google having my data. At this point, I'm resigned to the fact that I'm not going to have privacy, so my concern becomes #who has my data. Google has plenty of good reasons to want information, and while I'm not saying there's any guarantee that they're not doing anything nefarious, their track record seems to be pretty good on that front. Additionally, Google leverages the information they have on me to make my life more convenient, from the Google Now cards on my phone to the targeted ads which are generally more relevant to me than generic ads.
I think it's important to remember that privacy is not a boolean, but a spectrum; there are varying degrees of privacy. Some of the privacy we lost, we'll probably never regain, because I don't see drones and cameras disappearing any time soon; but we don't have to resign ourselves to the fact that Google can remotely install a microphone in our bedroom - we still have a say in that.
You're saying you're fine with Google indiscriminately recording private conversations that you have in your own home? I can sort of understand being okay with them knowing your online history (though even that shouldn't be allowed), but why would you be fine with them recording your conversations?
