Ray Kurzweil speaking with Amy Kurzweil at SXSW on March 13, 2017 in Austin, TX.

RAY KURZWEIL HAS invented a few things in his time. In his teens, he built a computer that composed classical music, which won him an audience with President Lyndon B. Johnson. In his 20s, he pioneered software that could digitize printed text, and in his 30s he cofounded a synthesizer company with Stevie Wonder. More recently, he’s known for popularizing the idea of the singularity—a moment sometime in the future when superintelligent machines transform humanity—and making optimistic predictions about immortality. For now, though, Kurzweil, 69, leads a team of about 35 people at Google whose code helps you write emails.

His group powers Smart Reply, the feature on the Gmail mobile app that offers three suggested email replies for you to select with a tap. In May it rolled out to all of the service’sEnglish-speaking users, and last week was presented to Spanish speakers too. The responses may be short—“Let’s do Monday” “Yay! Awesome!” “La semana que viene”—but they sure can be useful. (A tip: You can edit them before sending.) “It’s a good example of artificial intelligence working hand in glove with human intelligence,” Kurzweil says.

And Kurzweil claims he’s just getting started. His team is experimenting with empowering Smart Reply to elaborate on its initial terse suggestions. Tapping a Continue button might cause “Sure I’d love to come to your party!” to expand to include, for example, “Can I bring something?” He likes the idea of having AI pitch in anytime you’re typing, a bit like an omnipresent, smarter version of Google’s search autocomplete. “You could have similar technology to help you compose documents or emails by giving you suggestions of how to complete your sentence,” Kurzweil says.

Looking further ahead—as Kurzweil likes to do—all those ideas are eventually supposed to seem rather small. Smart Reply, he says, is just the first visible part of the group’s main project: a system for understanding the meaning of language. Codenamed Kona, the effort is aiming for nothing less than creating software as linguistically fluent as you or me. “I would not say it’s at human levels, but I think we’ll get there,” he says. Should you believe him? It depends on whether you believe Kurzweil has cracked the mystery of how human intelligence works.

Like Minds?

Google cofounder Larry Page oversaw some surprising initiatives during his second stint as the company’s CEO, from 2011 to 2013, including a robot acquisition spree, a new division to cure aging, and the ill-fated Google Barge. Hiring Ray Kurzweil in 2012 arguably ranks among those head-scratchers.

The company already employed some of the most influential thinkers in machine learning and AI, and was rapidly expanding its roster of engineers building machine learning systems to power new products. Kurzweil was known for selling books predicting a weird future in which you’ll upload your consciousness into cyberspace, not for building AI systems for research or useful work today.
