Increasingly, we’re surrounded by fake people. Sometimes we know it and sometimes we don’t. They offer us customer service on Web sites, target us in video games, and fill our social-media feeds; they trade stocks and, with the help of systems such as OpenAI’s ChatGPT, can write essays, articles, and e-mails. By no means are these A.I. systems up to all the tasks expected of a full-fledged person. But they excel in certain domains, and they’re branching out.
When OpenAI launched ChatGPT, with zero fanfare, in late November 2022, the San Francisco–based artificial-intelligence company had few expectations. Certainly, nobody inside OpenAI was prepared for a viral mega-hit. The firm has been scrambling to catch up—and capitalize on its success—ever since.
