TECH TITAN (COFOUNDER, MICROSOFT); GLOBAL PHILANTHROPIST (BILL & MELINDA GATES FOUNDATION); RICHEST PERSON IN THE WORLD (FOR NOW)
In early 1975, when I was in college, my friend Paul Allen showed me an issue of Popular Electronics featuring the Altair 8800 computer, the first commercially successful personal computer. We both had the same thought: “The revolution is going to happen without us!” We were sure that software was going to change the world, and we worried that if we didn’t join the digital revolution soon, it would pass us by. That conversation marked the end of my college career and the beginning of Microsoft.
The next 100 years will create even more opportunities like that. Because it’s so easy for someone with a great idea to share it with the world in an instant, the pace of innovation is accelerating—and that opens up more areas than ever for exploration. We’ve just begun to tap artificial intelligence’s ability to help people be more productive and creative. The biosciences are filled with prospects for helping people live longer, healthier lives. Big advances in clean energy will make it more affordable and available, which will fight poverty and help us avoid the worst effects of climate change.
The potential for these advances is thrilling—they could save and improve the lives of millions—but they’re not inevitable. They will happen only if people are willing to bet on a lot of crazy notions, knowing that while some won’t work out, one breakthrough can change the world. Over the next 100 years, we need people to keep believing in the power of innovation and to take a risk on a few revolutionary ideas.
