For our final trick, we'll inject some code. To jog your memory, here's foo() from the test program again:
Some ergonomic keyboards come with permanent or removable wrist or palm rests, which can be cushioned or hard. This is another area where opinions diverge: proponents claim they help you maintain a neutral hand position, while detractors say they put pressure on the tendons and can cause wrist pain or even exacerbate conditions like carpal tunnel. Ideally, your palms should be resting, not your wrists, and you might find you like having that support or you may find the pressure uncomfortable.

But by talking about why ATMs didn’t displace bank tellers but iPhones did, I want to highlight an important corollary, which is that the true force of a technology is felt not with the substitution of tasks, but the invention of new paradigms. This is the famous lesson of electricity and productivity growth, which I’ll return to in a future piece. When a technology automates some of what a human does within an existing paradigm, even the vast majority of what a human does within it, it’s quite rare for it to actually get rid of the human, because the definition of the paradigm around human-shaped roles creates all sorts of bottlenecks and frictions that demand human involvement. It’s only when we see the construction of entirely new paradigms that the full power of a technology can be realized. The ATM substituted tasks; but the iPhone made them irrelevant.
