I think the linked tweet is possibly just misinterpreting what the authors meant by “transistor operations”? My reading is that “1000″ binds to “operations”; the actual number of transistors in each operation is unspecified. That’s how they get the 10,000x number—if a CPU runs at 1 GHz, neurons run at 100 Hz, then even if it takes 1000 clock cycles to do the work of neuron, the CPU can still do it 10,000x faster.
Hmm I see it. I thought it was making a distinct argument from the one Ege was responding to here, but if you’re right it’s the same one.
Then the claim is that an AI run on some (potentially large) cluster of GPUs can think far faster than any human in serial speed. You do lose the rough equivalency between transistors and neurons: a GPU, which is roughly equal to a person in resource costs, happens to have about the same number of transistors as a human brain has neurons. It’s potentially a big deal that AI has a much faster maximum serial speed than humans, but it’s far from clear that such an AI can outwit human society.
