In my late-Victorian-based world, mechanical contraptions are incredibly advanced due to the early discovery and quick popularisation of mechanical computation.
The science of writing instructions for such machinery has allowed an effective AI ruler to come to power.
The insecurity I now face is how compact the parts required can be produced and assembled.
The parts used would probably be akin to those in this training video on a US-Navy mechanical computer.
What is the smallest I can possibly make a simple, 16-toothed gear wheel?
If you have any concerns towards possible problems of having such small machinery, such as lubrication or friction, please feel free to voice them.
