But after you have worked, say, 1 year to afford a toilet cleaning robot you will need a robot to mow your yard?
Now go work another year....
After that you must have a robot who can earn money for you to buy your food and pay for your VR goggles...
How long will that take? Perhaps you can clean someone elses toilet (who cannot yet afford a robot) until you have enough money to pay for your own toliet cleaning robots?
I don't know.
The aim is to have enough robots to generate wealth for me and allow me to live a life of leisure.
