Growing up in India, I was fascinated by technology. Each new invention changed my family’s life in meaningful ways. The telephone saved us long trips to the hospital for test results. The refrigerator meant we could spend less time preparing meals, and television allowed us to see the world news and cricket matches we had only imagined while listening to the short-wave radio.

Now, it is my privilege to help to shape new technologies that we hope will be life-changing for people everywhere. One of the most promising is artificial intelligence: just this month there have been three concrete examples of how Alphabet and Google are tapping AI’s potential. Nature published our research showing that an AI model can help doctors spot breast cancer in mammograms with greater accuracy; we are using AI to make immediate, hyperlocal forecasts of rainfall more quickly and accurately than existing models as part of a larger set of tools to fight climate change; and Lufthansa Group is working with our cloud division to test the use of AI to help reduce flight delays.

Yet history is full of examples of how technology’s virtues aren’t guaranteed. Internal combustion engines allowed people to travel beyond their own areas but also caused more accidents. The internet made it possible to connect with anyone and get information from anywhere, but also easier for misinformation to spread.
