I like analogies so I'll ad my own. Its like a leatherworker not knowing anything about how a hide is tanned. Or a tailor not knowing how fabric is woven.

It's really really important to the trade to understand the process in which their base materials are created. They don't need to know the exact skills of creating those materials to the degree of someone at a Tannery or a Mill. But it's important to the work of both of those trades to understand the basic process. And really I don't think a leatherworker or tailor could be considered to hold either of those titles if they didn't understand the basics.

We don't have that with modern tech. The materials and tools that modern workers use appear as complete black boxes to them. Like magical black boxes. And it's honestly, a fundamental incompatibility with the incentive structures of existing economic systems that were forced upon a technology that should have made them obsolete in the 90s. But I digress.
