- JoeAltmaier 8y agoNeurons are already logic gates. And FFT devices, and discriminators and ...
- TeMPOraL 8y agoSo basically neurons are ASICs, partially digital and partially analog.
- JackFr 8y agoThey're basically cogs, rods and gears. Seriously, molecular biologists devote decades of study and publish volumes figuring out how some small virus 'works'. A human neuron is orders of magnitude more complex than such a virus. To dismiss it as 'like an _____', is a (sometimes necessary) analogy of very little explanatory depth.
- JoeAltmaier 8y agoMetaphors help understanding. A neuron is more on the order of an entire logic subsystem, than a transistor or a gate. That's a reasonable comparison-of-complexity statement.
- TeMPOraL 8y agoI'm not dismissing things. In fact, 'JoeAltmaier is correct that my analogy here was in context of the usual "neuron as signal adder" / "neuron as transistor". And yes, I'm aware neurons are complex. But that does not mean all of that complexity is relevant to the task of thinking; all living cells have machinery related to self-replication, self-maintenance and survival in a biological system. Or to use another analogy - a smartphone is orders of magnitude more complicated than a flashlight. Yet in context of people illuminating their way during the night, a smartphone is just a flashlight.
