To feed the data centers with yummy personal data. No dataset is to big, no picture of the side of someone's arm is too pointless. We must consume all data

FOMO. Every experience is recorded just in case you (or really the government) might ever realize it was missed. Just in case it ever becomes interesting.

I record all my phone calls. It allows me to pretend not to forget all the names, dates, places and other important details we just talked about with the other person as soon as the call ends.
