Dunno what made me think of this just now. When I worked for IT in a school district way back in the 90s, a librarian told me she kept a supply of mouse balls in her desk because kids would steal them out of the school computers. What I remember about those balls was they picked up dust and crud off surfaces. Pretty soon optical mice came along and they were history.
This thread makes me wonder if there will always be a mischief factor. Even if robots do all the work and we can have anything we want for free, will people still want to fuck shit up just because they can?
Sometimes thought experiments can be pretty revealing…
Absolutely. If humans disappeared for two months every object in the world would be on the floor. Then cats, having fulfilled their mission, would suddenly vanish in a puff of loose hair.
