We’ve been presenting our list of innovators under 35 for 18 years, long enough to spot some trends. You won’t find a lot of artificial-intelligence innovation in the early days of the list, but AI now dominates. And the list has grown more gender equitable. It was once male-dominated, but this year, for the first time, it includes more women than men. We hope the list gives you a sense of what’s coming next, and what kinds of people are making it happen.
