Electronics (Computers)-0 - anyone living in the Imperium on a world higher than TL-8 should learn this in School
Curious how you think that manifests in todays world. A simple example, I had a blood draw recently, and the phlebotomist obviously had to use a rather complicated application to manage my appointment info, personal info, keying in the labs to do, printing labels, etc.
So, she understands mousing, and clicking, and keyboard actions. Do you consider that "Computer-0"? I assume she knows how to turn the machine on, perhaps log in, and start the program (if they even shut the things down at night).
But does she know anything about computers? What those wires do coming out the back, anything at all about the architecture? The OS?
There are likely millions of people that are Driver-1 and not even Car-0. Who may consider opening the hood to void the warranty. "When the light goes on, I take it to the dealer."
The beauty is, of course, that folks nowadays don't have to know much about cars in order to operate them. Driving? Yes. Dynamics, steering, braking, traction, etc. Mechanics? No.
You don't need to know anything about computers to operate an ATM.
So, just curious what you consider "Computer-0" to be in todays world.
