Watching TV is a social activity - gathering at a friend's place to watch a new episode, or relaxing with family.
The future implied by these developments is that TV-based tracking will take the home audience into account, and the screen becomes -- in some sense at least -- a camera as well as a display.
Instead of being shown subtly inadequacy-leveraging ads on your own device, now they're going to be interwoven into you and your family's home in such a way as to influence thoughts and opinions.
Gradually adtech will - as it has already - erode the ability to have peaceful, genuine social human interaction while enjoying an artist's intended work uninterrupted.
I'd like to think that alternatives to advertising finance are on the horizon, because the ad business seems to further income inequality. Adtech employees deny and avoid their guilt by enjoying the profits they make, while their audience (who are increasingly also their acquaintances, as peer-based referrals and influence marketing heat up) are pressed to spend and consume, often unnecessarily.
I'd wager the trend towards ads and quantified influence is going to continue until it necessitates radical change.
NB: In reality the capability likely already exists to target ads based on who you're currently with, so this is really just an opportunity for the advertising industry to socialize and normalize these practices.
