> I actually believe it is both robotic-type of automation It doesn't even have to be automation. A lot of it is just enormous scaling up of equipment. For example, road building used to take hundreds or thousands of people with shovels and wheel barrows. Now it's a crew of ten or twenty people driving enormous earth moving machines. Same with farming. What used to be a guy with a horse pulling a single row planter is now a guy in a tractor with a 40 row planter. A lot of productivity gains in industry are similar. Things get scaled up to ridiculous levels that people a hundred years ago couldn't even dream of.
