美國到底在幹什麼？伊朗戰爭正在動搖中國的雄心
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.

Hole soil analysis also found ancient pollens of maize – a key staple in the Andes – and reeds traditionally used for basket-making. In addition to this, there were traces of squash, amaranth, cotton, chili peppers and other crops that haven't been farmed on the arid land where Monte Sierpe sits. Because many of these plants produce little airborne pollen, it's unlikely they settled in the holes naturally. Instead, the researchers believe, people carried goods to the site and deposited them in the holes, likely using baskets or bundled plant fibers that were periodically replaced.
