The raw sensory inputs to a human brain must also be jittery. Eyes apparently see highest definition detail only in a tiny area of the visual field, for example. The brain stitches it together, interpolates, tags features, and guesses. The preprocessing miraculously creates the impression of a big clear image out of a dirty data feed from two jello cameras that are swiveling around all the time. There's a lot a smoothing going on. Imagine if you could see the raw input from an eye - it would be a big field of view, but mostly blurry, mostly not in full color, with a blind spot hole near the center, and the whole image jittering around violently. One trait of practical real-world intelligence is ignoring 99.9% of everything. It usually works.
