I'd be real surprised if the neurons in our brains have ADC-equivalents better than ~4 bits.

True, but ANNs are nowhere near as good as our brains, nor do they operate in the same way.

I think you missed the fact we were talking about neural network, not an animal brain self replicating and branching and competing with itself for billions of years until it becomes aware of itself. Give us the the same time.

  The earliest and simplest brains where still useful. Even insects can fly around in 3D space, I doubt you need something as complicated as a mouse brain to run a self driving car let alone a drone.

    I’m not sure how much it matters given this thread looks like it’s going off on several successive tangents, but the important (and hard) thing with a self-driving car is making sure it doesn’t hit stuff, not the actual driving part. And drones, trivially agree: Megaphragma mymaripenne has 7400 neurones, compared to the 71/14 million in a house mouse nervous system/brain.

      And to stay on this odd tangent: Best estimate I have for total cell numbers in mouse brain—about 75 million neurons and 35 million other cell types. This estimate is from a 476 mg brain of a C57BL/6J case—the standard mouse used by many researchers. Based on much other work with discrete neuron populations the range among different genometypes of mice probable +/- 40%. for details see: www.nervenet.org/papers/brainrev99.html Expect many more (and I hope better) estimates soon from Clarity/SHIELD whole brain lighsheet counting with Al Johnson and colleagues at Duke and team at Life Canvas Tech.

    Insects also crash into stuff constantly!

      Bats do, too, despite being much smarter than insects. It seems nature prefers the "fail often and recover quickly" system.

        They are simply too light to hurt themselves.
