Sure, I supposed you could calculate a limit by looking at how many human eyes there are, how many frames per second they can see, and max resolution visible. That still isn't actually a limit on how many images could be made, only how many could be consumed.

That said, if we got to such a massive scale I'd expect us to hit other limits first (electricity available, best produced, storage space, network transmission, etc.).

Or did I totally misunderstand your example here? I may have misread it completely, if so sorry about that!

Sure, absolutely. But I can say the same of food, which is why I drew the analogy between them previously.

Difficult to guess when the quality isn't yet at the right threshold: GANs are already this speed on phone hardware*, so we're not bounded on that specific combination with available electrical energy; on the other hand, 2 years ago I was seeing images for about 3 kJ, which is in the region of hundreds of kilowatts for 2 eyes at 60 fps, which is absolutely going to be a problem… if they were limited to that hardware and with that model (though both are moving targets, I'd be very surprised if the unknown hardware that I've seen doing 4-5 fps was burning 12-15 kW, but it's not strictly speaking impossible it really was that power hungry).

* Specifically: on an iPhone 11, BlazeStyleGAN model was generating images in 12.14 ms, which is just over 82 fps — https://research.google/blog/mediapipe-facestylizer-on-devic...
