Massive scale automation for environmental cleaning.
At one time of day if you said to a hardware expert you are going to be able to fit billions of transistors onto a single silicon chip they would say it’s not possible at the moment and it might be possible in ten years. This is the kind of feeling I get when I consider this idea: Massive scale automation, humanoids, robots cleaning the entire environment down to every leaf on every tree. These robotic automated systems work silently throughout the night and return to their charging hangar before sunrise. These robots repair the roads, unblock drains and gutters, clean windows, clean vehicles. Customer services might get a call like ‘The overnight automated cleaning didn’t clean my Bentley very well and I’d like to complain’
