Amid today’s technological wizardry, it’s easy to forget that several decades have passed since a single innovation has dramatically raised the quality of life for millions of people. Summoning a car with one’s phone is nifty, but it pales in comparison with discovering penicillin or electrifying cities. Artificial intelligence is being heralded as the next big thing, but a cluster of scientists, technologists and investors are aiming higher. In the vernacular of Silicon Valley, where many of them are based, their goal is nothing less than disrupting death, and their story is at the center of “Immortality, Inc.” by science journalist Chip Walter.

The efforts of scientists and investors to defy the aging process—and extend the human life span—are still in their infancy.

Tech giant Apple has acquired Xnor.ai, an artificial intelligence startup that came from Microsoft co-founder Paul Allen’s research lab. The acquisition suggests that Apple may be planning to Xnor.ai’s machine learning tools int iPhones and iPads in the future, with processing on-device instead of in the cloud.

GeekWire first broke the news earlier Wednesday, citing sources with knowledge of the deal. According to GeekWire, the deal is reportedly worth up about $200 million. Apple paid the same $200 million for another Seattle-based AI startup, Turi, in 2016.

Unlike traditional AI that runs in massive data centers and requires network connectivity, XNOR makes AI highly efficient by allowing deep learning models to run directly on phones, IoT devices and low power microprocessors. XNOR’s technology enables AI experiences that are up to 10x faster, 200 percent more power efficient, and use 15x less memory.
