Re:Rise of the Creative Class Worked a Little Too Well

Sure, there's some creating work in dealing with obstacles. But let me give another example. My house was wired up by an experienced electrician. I noticed he was running the phone wires through the same holes as the A/C wires. I told him that would not work, as the phone wires would pick up the 60 Hz hum by inductive coupling. He had never heard of the term "inductive coupling". He had NO IDEA what I was talking about. If I let him continue, the phones in my house would all hum.
So I told him I'd do the low voltage wiring myself. Those have to be separated from the A/C wires by a couple feet, and only cross them at 90 degree angles. No hum.
Inductive coupling is something a first year EE student would learn about.
To a degree. I get the contrast you're drawing and don't really disagree. But an electrician (like plumbers/contractors/etc.), especially working in an older building, has to deal with a lot of unexpected circumstances that have to be dealt with. There's a lot of problem-solving involved.
