I think what the author is saying is akin to that old joke about a broken machine that nobody at the company can fix.

They bring in a high priced consultant who spends a few minutes looking at the machine, reaches in and pushes a switch and suddenly the machine starts working.

When the manager gets the invoice, he calls the consultant demanding an explanation for why it cost so much. After all, the consultant only spent a few minutes looking and then flipped one switch.

The consultant offered to send a more detailed invoice and the manager received one that said:

- Flipping a switch: $1 - Knowing which switch to flip: $999

In other words, the writing of the code is like flipping the switch. It’s the rest of “coding” that’s difficult.
