I seem to remember having a lot of the same feelings during the Apple event last month. The Nike+ Apple Watch will "helpfully suggest gear" for your workouts.

Ads have become utterly pervasive, and avoiding using Google's AI isn't going to protect you from them. My Samsung "Smart" TV has ads for Hulu built right into the operating system (despite my being a Hulu subscriber at the time). Windows 10 is basically one big advertisement (at least the consumer edition).

If I have to have ads blasted in my face all the time, I'll take Google's AI-driven ones that at least stand a chance of being less annoying.
