In an alternative universe Elon-5000 is slowly figuring out that his plan to fully autoprimate his vehicle plants using the latest in primate tech- humans; slow and weak swarm entities that are extremely cognitively flexible, cheap, energy efficient (fueld by almost anything green), with built in error checking, is not working out. A mix of traditional robotics from the 80s and advanced primate tech will be most efficient.
