At Km67 of the Ushuaia 130K ultra — Tierra del Fuego, end of the world — Enzo Duit's knee was failing. Heart rate 155. 64km still to go. He had two data points: his Garmin Enduro read his exact cardiac load, and his autonomous AI agents had been running three business processes uninterrupted for 31 hours while he raced.
He didn't stop. He adjusted pace based on the data, finished in just over 31 hours, and checked his agent logs at the finish line.
That's the actual life Enzo is documenting: not the polished version of "I optimize for performance," but the raw intersection of physical extremity, AI autonomy, and what happens when you build systems that don't need you.
