“Quick! How can we use this to gather data for ad targeting?”

Amazon with all its power and incentive still can’t figure out there’s a limited number of toilet seats I might need. Linkedin is still offering me (50ish male, 30+ years in it, 15+ years of teaching in universities, board member etc) jobs as a kindergarten teacher. If anything, I’m amazed they are still so bad at this.

Heh, people detection, gaze detection and people hotspots detection (i.e. where people mostly stand, say at an intersection) have been a thing for 15-20 years now, I consulted on such a project in the 2000s, using simple mobile cameras that were placed in a van, the van moved, and they'd make "maps" and sell that data to advertisers who chose where to place fixed/changeable ads banners. They eventually got that data from cell providers, and didn't need the cameras anymore.

So much data collected for targeting ads, only to finally conclude that the only product I'm interested in buying is a handful of cool mmWave sensors from Infineon.
