The rapid advancement of artificial intelligence—the discovery of mind-bending use cases and launch of new businesses—has warped my sense of time. Suddenly, leaps in computing that previously took years seem to be unfolding in weeks. When I first wrote about ChatGPT, back in December, I described my excitement about how A.I. could potentially transform art and industry, but also my fears about mistakes and unintended consequences along the way. It was this same concern, after all, that led Sam Altman and Elon Musk, among others, to found OpenAI, the company behind ChatGPT and Dall-E, with a mandate to develop these tools in the safest possible way.
