Google CEO Sundar Pichai unveiled a version of Duplex that was tamer than last year’s. James Martin/CNET From the very moment Google pushed play on a mundane recording of a guy booking a dinner reservation last year, the search giant became embroiled in an intense debate over the ethics of artificial intelligence.The unremarkable nature of the recording was what made it so unnerving. The guy wasn’t a guy at all. It was Google Duplex, a chatbot that uses AI software to mimic human speech with startling accuracy. The audience at Google’s I/O developer conference freaked out over the verbal tics — “uh” and “um” — that the software used and the natural way it pronounced certain words. Duplex had the potential to stir controversy again if Google unveiled another big chatbot development during this year’s conference keynote on Tuesday. Instead, the company offered a subdued, though impressive, update.That’s probably for the best.

But for Google, that’s a win. The company has drawn blowback for its AI operations, including a March backlash over its artificial intelligence ethics board. Google disbanded the board after only a week.“Duplex on the web” automates booking of rental cars and movie tickets. James Martin/CNET The company is also still reeling from its contract with the Pentagon for Project Maven, a defense department initiative that uses AI to improve the analysis of drone footage. The effort caused an uproar among Google employees.A handful of workers resigned, and more than 4,000 workers reportedly signed a petition addressed to CEO Sundar Pichai demanding that he cancel the project. Google eventually said it wouldn’t renew the Maven contract or pursue similar contracts, though it would still work with the military. Pichai wound up publishing an entire AI ethics memo that stated the company wouldn’t develop the technology for use in weapons.After those dustups, it behooved Google to lie low this year and turn down the creepy AI. And the company certainly learned its lesson last year, Scott Huffman, head of engineering for the Google Assistant, told me earlier this year. “The strength of the reaction surprised me,” he said, referring to Duplex’s debut. “It made it clear to us how important those societal questions are going forward.” Android 10 beta’s best new tricks from Google I/O 2019 Comments Mobile Software The new feature is called “Duplex on the web” and it’s basically autofill on steroids. While the original Duplex was for restaurant reservations and hair appointments, the new version automates booking rental cars and buying movie tickets. It zips through forms on the mobile web, automatically entering information that Google knows about you from your calendar, Gmail inbox and Chrome autofill. Some people might still find it unsettling that Google knows so much personal information about you. But the Duplex upgrade provoked nowhere near the response Google got for last year’s human-sounding robot and its ability to fool the people it was talking to. Compared with that spectacle, this version is downright boring. And boring is pretty good for booking a midsize sedan for your trip to wine country. “The strength of the reaction surprised me.
