Ben, as you well know, my estimate is not for a detailed brain emulation. It is for a neural network with approximately the same number of synapses and response time. Each synapse requires one multiply and one add operation per cycle, or 2 of each if updated. That is a vast simplification of the behavior of real neurons, but sufficient to get equivalent high level behavior according to generally accepted theory. It seems very convenient that your estimate of computing power for AGI exactly matches the computing power you have available. And yet people with thousands of times more computing power have only been able to solve much easier problems like recognizing cat faces or winning at Jeopardy. So I would really like to know how many nodes and links (OpenCog, DeSTIN, or otherwise) you need for AGI. How many concepts and how many relations? How do you get these numbers? I explained my estimate of 10^7 features and 10^13 relations for vision. You need to explain why those numbers are wrong. Intuition is not an explanation. > In a similar way, you could prove airplanes can't fly by tabulating > the number of computations implicit in the activity of a bird's cells No. I can estimate how much energy is required to transport a given amount of weight by an airplane by measuring it in birds. That works because evolution and the airline industry have both put a lot of work into optimizing it. By a similar argument, we don't have human level intelligence in insect sized brains, or in machines of equivalent computing power.
