Brain-wave-scanning kind of invasive. FB (and advertising in general) will continue to become ever more invasive until it meets a limiting factor. That limiting factor will possibly be legislation (just not in the US because worshiping the Dollar overrides anything and everything else).
Do we know the first thing about how brain waves correlate to any real world properties of a person? If Facebook or anyone else can crack brain waves, ie in a sense "read your mind", it seems like serving ads is the least of our worries, but also pretty exciting in terms of the potential positive applications.
It is not exactly clear to me whether you are down playing the implications or not, but lets assume you are:
If this weren't invasive, they wouldn't be doing it. What use would random data be to Facebook? Also, it is irrelevant: if I buy a VR set I want to use it for whatever I see fit, not get hooked into some data collection machine. How is it that we have come to accept that in order to use products, that we buy even, we have to hand over lots of data?
I'm not. I believe that this kind of data in combination with machine learning makes for the perfect storm. While users may not understand the difference from before.
Sounds like machine learning in this case would lead to GIGO as essentially automated superstition. It would get what, use time, how much time is spent moving using it and maybe height data and try to map to products the advertisers want to sell?
