A proof of existence inspires and sustains the greatest ambitions. The Imitation Game, a test of whether a machine could exhibit human-like intelligence through conversation, gave us a target to chase in advanced machine intelligence. The sun has been producing clean energy at scale, through fusion, for billions of years. Nature makes energy and intelligence on its own, but not in the quantities we need. In chasing the discoveries embedded within these proofs, engineers, researchers, and entrepreneurs can make scarce things abundant.

One year ago, Matt Osman and Fabio Boniolo set out to build Polyphron, a human tissue foundry inspired by the proof of existence each of us carries. Human development shows that a single cell can give rise to a liver, kidney, and heart. Biology runs this process billions of times over, but does so once per person and never on demand. Polyphron is building the machinery to produce human tissue at scale.
