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.
As with most everything, changes viewed gradually are taken for granted. But when viewed all at once (as a time traveler might see them), a smartphone plus the internet would seem like complete and utter magic.
