To make the neuron network be a strong AI, we may need the parameters in scales of 10^19~10^44 (uncertainty limit and Planck time) estimated from how many frames per second in real world.
I personally got a feeling that this is bound to how nature calculate the physical phenomenon. For simulation, there are lots of "for loop" in our code/machine. But, in real world, we could not observe any "for loop". It is fast and continuous in the macro scale.
In order to reach strong AI, it is time to focus on quantum computing.
