It’s not. We’re analogizing to the latest technology, as we always do.
We found analogous forms. I think it’s a great thing! Still an analogy though. Considering we’re a PART OF the very Universe and created systems WITHIN the same Universe it’s logical that we would mimic some of the same systems of the Universe in our creations.
But the computer is ultimately based upon our conceptions of the Universe, not the universe off of our conceptions of the Universe.
Another mistake we make is: “the brain is like a computer”.
But it’s really: The computer is like a brain.
