Automobile engines are also very complex, but no one talks about no-mechanic cars. In highschool where I grew up, the bottom academic 50% of boys ended up being mechanics of one type or another. At one point in time, being an auto mechanic was an elite, rare profession, and that complexity was encapsulated as something that low-performing academic students could bank on for a career.

I see the exact same thing with code: the complexity is eventually abstracted away until it becomes a vocation that doesn't require a college degree (think mechanical engineer vs mechanic, computer scientist vs programmer).
