> AGI needs to keep in touch with a consensus reality I very much doubt it, I think it is enough for AGI to "prove" it can develop increasingly better views of its reality, at its own pace, if an AGI passed the Turing test taking an hour for each of its answers I'd be OK with that. Also, taking a clue from biology, we do seem to have the fast and the slow nervous system as well as engineering solutions like the retina and optic nerve being "glued" on the brain rather than the ankles, in no way pretending to do reality acquisition, rather defining "real time" by their own working tempo, anywhere from 20 to 100 fps. Perhaps the brain can do some reading at 10 and 20 fps but none at 100fps, and that's that, there seems to be no cache that, after closing one's eyes, allows the processing of a backlog. But we do have a backlog mechanism when it comes to General Intelligence, we can close our eyes and work through a problem domain for seconds, minutes or even longer, with no real-time constraints really. Now, the "social" aspect of intelligence is very important, and it is great that we could both in a split second agree about the contents in a room, while even 10 years in a room would not be enough to agree on Palestine or the Greek debt. For real-world mixed man-machine applications it would be important to achieve human-time performance, but not "of the kind" that would look like a physics simulation forcing us to tackle some analog-to-digital issues in the sense of the article you are quoted. For what it's worth I believe that very sparse and cruel representations will suffice or even are necessary. I am also convinced that "multiresolution" representations will have to be included in any design, analogous to our short and long term memory - I am just a bit skeptical of trying to "program in" our mind models, for example limiting the artificial short term memory to 7 items. All of the above applies to a kind of "finished product". But during the design and evolution of an AGI I have stated elsewhere that indeed one could ride the real-time horse, emphasizing the responsiveness of the machine. One could, for example, explore the capabilities of one of these enormous CUDA cards or FPGAs, acknowledging that you could never respond faster than so many nanoseconds (FPGAs being much slower). Then again, the optimal "system dimensioning" is the one that includes your sensors and actuators, if you can only send commands to your motor 10 times a second, then why would you read your body temperature 100 times a second and analyze your state 1000 times a second, you are better off running the analysis a split second before sending it to the actuator and use 99% of your "horsepower" for something else, but what! Biological evolution in these cases follows closely the physical constraints of survival and reproduction and would not couple a nanosecond brain with a millisecond muscle. Our engineering is much more arbitrary and we would find something to do with the extra cycles, probably involving longer time scales. However that "something" would not have to consider analog domains at all.
