Earlier quoted context omitted.
You interpretation of his analogy is what he wants I think. If learning how to change your oil is like learning to install that new wifi dongle, then you should know how to do that. You certainly don't need code to do that. Similarly you don't need to be a mechanic to change oil.
You don't need to be a mechanic to change oil, but a small amount of mechanical knowledge helps quite a bit. I am talking about knowledge such as what is a drain plug, what is oil, what is an oil filter. Most people have at least a rudimentary knowledge of how a car works. Computing is still magic to many people, and it should not be.
Nowdays the complexity of car has turned it into "magic", too. Choosing the wrong oil weight for a modern turbocharged car will wreck the turbo and the engine. Another example is the new style of oil filters. They are cartridge style with very delicate torque specs. an over torqued oil filter housing cover will create a significant drop in oil pressure due to to a leak.
Heck, even changing a tire is now a mess due to the recently implanted tire pressure systems.
