This is for all the wet-behind-the-ears #TechBros who hold the highest fantasies about building a future of AI, Tesla vehicles, and manufacturing plants all run by robots.
I ran across an article about how Teslas with significant mileage on 'em are running into maintenance issues, cure for which is to just buy a new Tesla. All you born-yesterdays had better come to grips with the fact that machinery requires maintenance, and if you think no prob because robots can fix robots, you're neglecting the requirement for replacement parts. Robots require more frequent replacement of parts than humans do because a part is worn out when its movement becomes too sloppy to respond to calibration.
Robotics requires tight tolerances and even when a part still functions, it'll be operating out of tolerance and when the slop can't be compensated for by software, the parts require replacement.
