I am. I'm referring to my brain in a "tech industry buzzword" way. It is, technically speaking, a trained neural network. Just a biological one, not a silicon/code based one. I happen to like it, and it can also do things like tell the difference between a low moon in the sky through a smoke haze and a traffic light.

"If there are any positives, then the technology is worth using!" style thinking misses, entirely, the concept of opportunity cost, and the various downsides.
I won't argue that it's not pretty cool to see everywhere you've been - but it's also an exceedingly detailed record of who you are, and anyone who claims it can be suitably anonymized is full of crap (see the Grindr Bishop for a solid case study here).
Where I really start to get upset, though, is that there's no opt-in for this, other than some vague, generic, "nobody reads this and it doesn't say anything anyone would understand anyway" clickthroughs.
Android doesn't have a, "Would you like us to keep a record of your location and everywhere you've been? You can review it later and see what cool places you've been!" sort of opt-in. It just does it.
Google clearly is getting some value from that data, and it's not at all clear what it is.
