'Mario Never Dies': Agent Forks the VM Into 4 Timelines Every Death to Pick a Survivor

TheMoonMidas · x · 2026-09-19

Developer @theappcypher built "Mario Never Dies" using @typesafeai's Jev model plus the microsandbox VM. Jev picks every move in Super Mario Bros., and every time Mario dies, the entire virtual machine is forked into 4 parallel timelines and retried. Whichever Mario survives becomes the canon timeline, as if the others never happened — a playful implementation of the author's take on quantum immortality. Beyond the humor, it's a counterintuitive demo combining model-driven control with VM snapshot/fork infrastructure, hinting at novel fault-tolerance ideas for agents.
