For example, when gears were high tech there were people that drew heads with gears turning inside of the head, likening the act of thinking to the motion of gears. And I think in cartoons etc we still see this sometimes.

Computer analogies are different. These are direct, not metaphorical, and rightfully so, because computation is fundamental and not just a piece of technology. Computer science stands at the intersection between mathematics and physics.
Heck, even the operating system could reproduce in some sense. If the operating system on one machine is set up to regard itself as DHCP server, it would begin responding to DHCP requests in the local network. And in the DHCP response it can provide network boot instructions telling other computers to network boot a copy of the OS image of itself that it is serving. Any other computer that is configured to net boot could then boot the OS. Of course most computers are not set up to net boot out of the box. But on a network where they use net boot already you might be able to race their own DHCP server and get some of the clients to boot your OS image instead.
