A secretive, Google-backed lab is using artificial intelligence to invent new medicines for humanity's worst illnesses. But can we trust drugs designed by a mind that isn't human?

Deep inside Alphabet, the parent company of Google, a secretive lab is working on a promise so audacious it sounds like science fiction: to “solve all diseases.” The company, Isomorphic Labs, is now preparing to start its first human clinical trials for cancer drugs designed entirely by artificial intelligence.

In a recent interview with Fortune, Colin Murdoch, President of Isomorphic Labs and Chief Business Officer of Google DeepMind, confirmed the company is on the verge of this monumental step. For anyone who has watched a loved one battle a devastating illness, the hope this offers is immense. But for a public increasingly wary of AI’s power, it raises a chilling question: can we really trust a “black box” algorithm with our lives?
