A technology demo can be both incredibly cool, while still having significant negative implications. 16-year old me dreamed about this sort of tech.

Technology is a tool, neither intrinsically good nor evil. Unfortunately the tech industry has, as a whole, shown a stark disrespect for the needs or desires of individuals. Tech culture values monetization over individual autonomy, and that shows little sign of changing. Unfortunately, without a dramatic culture shift, it will continue to be the case that otherwise amazingly incredibly cool tech like this gets subverted to force more "personal" interactions.
