I don't agree. For those onboarding onto the subject, their mental model will be focused around the higher level details implemented around the application layer. The physical layer only starts to become remotely relevant once you start to delve onto very specialized topics.
I highly doubt even 1% of engineers could describe how WiFi works on the radio / physical level let alone anything about the variosu ways we make wires and light works.
