If it does this an infinite number of times the simulated DDD never reaches its own return instruction. If it does this a googolplex number of times the simulated DDD never reaches its own return instruction. If the simulation is ever aborted the simulated DDD never reaches its own return instruction. When we construe the halt state of DDD as its "return" instruction then the simulated DD never halts. -- Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
