I think the 'grow at 10%' refers to the incremental part of the entire world/market.

during the industrial revolution(steam/electricity/internet), the world was growing, there're trains, cars, netflix

bussiness grown with productivity growing, even so, we lived through 2 world wars and dozens of economic crisis

but now is very different, when you repair the tank with LLM's help, when the labour value of repairers is decreased, there's no addition value are produced

there's a very simple thought experiment abt the result of productivity growing alone:

let's assume robotics become to a extremely high level, everything humen work can be reduced to 1/100 with help of robots, what will happen next?
