Over the past few months, many have attempted to translate the uncanniness of Gov. Ron DeSantis' smile into words. After the Republican debates, it's been called "painfully weird" and said to look "like it's on his face upside down." It resembles "a Disney World animatronic" or "an A.I. trying to learn human emotions." It even inspired The Daily Show to put out a public service announcement about "Frownington's Disease," a made-up condition that causes a person's smile to resemble a wince one would make upon "sitting on his own testicles." As nice as it is that one expression has inspired such rich verbiage and creativity--Ron DeSantis, unlikely muse!--you might find yourself longing for a more technical explanation.

Earlier this year, the technology company OpenAI released a program called DALL-E 2, which uses artificial intelligence to transform text into visual art. People enter prompts ("plasticine nerd working on a 1980s computer") and the software returns images that showcase humanlike vision and execution, veer into the bizarre, and might even tease creativity. The results were good enough for Cosmopolitan, which published the first-ever AI-generated magazine cover in June--an image of an astronaut swaggering over the surface of Mars--and they were good enough for the Colorado State Fair, which awarded an AI artwork first place in a fine-art competition. OpenAI gave more and more people access to its program, and those who remained locked out turned to alternatives like Craiyon and Midjourney. Soon, AI artwork seemed to be everywhere, and people started to worry about its impacts. Trained on hundreds of millions of image-text pairs, these programs' technical details are opaque to the general public--more black boxes in a tech ecosystem that's full of them.

For years now, artificial intelligence has been hailed as both a savior and a destroyer. The technology really can make our lives easier, letting us summon our phones with a "Hey, Siri" and (more importantly) assisting doctors on the operating table. But as any science-fiction reader knows, AI is not an unmitigated good: It can be prone to the same racial biases as humans are, and, as is the case with self-driving cars, it can be forced to make murky split-second decisions that determine who lives and who dies. Like it or not, AI is only going to become an even more omnipresent force: We're in a "watershed moment" for the technology, says Eric Schmidt, the former Google CEO. Schmidt is a longtime fixture in a tech industry that seems to constantly be in a state of upheaval. He was the first software manager at Sun Microsystems, in the 1980s, and the CEO of the former software giant Novell in the '90s. He joined Google as CEO in 2001, then was the company's executive chairman from 2011 until 2017. Since leaving Google, Schmidt has made AI his focus: In 2018, he wrote in The Atlantic about the need to prepare for the AI boom, along with his co-authors Henry Kissinger, the former secretary of state, and the MIT dean Daniel Huttenlocher. The trio have followed up that story with The Age of AI, a book about how AI will transform how we experience the world, coming out in November.
