Looks correct to me (except 4e15 is a peta- rather an exa-, but that's tangential and doesn't seem to affect your real conclusion, the "factor of 1M"). The "facial recognition" must be me misremembering the original writeup, which I still haven't found.
It's probably lame to double down on this point, but, gigapixels is definitely enough to contiguously track people back to their homes and workplaces, which gives you like 90% of the benefit of facial recognition (for, as you point out, 1e-6 of the cost).
- tonyarkles 4y agoThanks for the correction! I was in the tub and not really in the "SI units" headspace :) And yeah, continuous tracking of people is definitely viable, including entire crowds of people. A couple of years ago our local football team did a gigapixel photo of the entire stadium (on a 360 degree pan mount) and you could very easily manually pan through the photo and identify faces very very clearly. Tech to do that in real-time is definitely here and readily available.
