When Fortune 50 companies want more precise AI, they often call Wendy Gonzalez, CEO of Sama — a company that has workers in rural Uganda fine-tuning the AI models for self-driving cars.

Microsoft CEO Satya Nadella testified in federal court Monday that Google has unfairly hobbled his company's effort to compete in search — and that advancements in artificial intelligence likely won't change the landscape enough for Microsoft to catch up.

Future-of-aviation startup Beta Technologies has opened the doors of a net-zero production facility, where it will make both conventional and vertical takeoff and landing (VTOL) electric aircraft.
