I've written often about how useful -- indispensable, even -- our smart phones have become in just a few short years. This says it much better:
A well-educated time traveller from 1914 enters a room divided in half by a curtain. A scientist tells him that his task is to ascertain the intelligence of whoever is on the other side of the curtain by asking whatever questions he pleases.
The traveller’s queries are answered by a voice with an accent that he does not recognize (twenty-first-century American English). The woman on the other side of the curtain has an extraordinary memory. She can, without much delay, recite any passage from the Bible or Shakespeare. Her arithmetic skills are astonishing—difficult problems are solved in seconds. She is also able to speak many foreign languages, though her pronunciation is odd. Most impressive, perhaps, is her ability to describe almost any part of the Earth in great detail, as though she is viewing it from the sky. She is also proficient at connecting seemingly random concepts, and when the traveller asks her a question like “How can God be both good and omnipotent?” she can provide complex theoretical answers.
Based on this modified Turing test, our time traveller would conclude that, in the past century, the human race achieved a new level of superintelligence. Using lingo unavailable in 1914, (it was coined later by John von Neumann) he might conclude that the human race had reached a “singularity”—a point where it had gained an intelligence beyond the understanding of the 1914 mind.
The woman behind the curtain, is, of course, just one of us. That is to say, she is a regular human who has augmented her brain using two tools: her mobile phone and a connection to the Internet and, thus, to Web sites like Wikipedia, Google Maps, and Quora. To us, she is unremarkable, but to the man she is astonishing. With our machines, we are augmented humans and prosthetic gods, though we’re remarkably blasé about that fact, like anything we’re used to. Take away our tools, the argument goes, and we’re likely stupider than our friend from the early twentieth century, who has a longer attention span, may read and write Latin, and does arithmetic faster.
The article is an exploration of whether our technology isd making us smarter or dumber. A little bit of both, I suspect is the right answer. We can certainly do more and learn more with greater ease than ever before. But we're not using our brains for things the way we once did. Take away our tools, and we might be more ill-equipped that ever to cope with the world.
