Labor saving tech doesn't lead to more free time, and certainly not in a way that's proportional to the gains of automation. Instead, companies will expect still more productivity. Why give you more time off if they can keep workdays fixed and add still more productivity? Certainly, the competition will do it.

It does when you own the tech. If you give the tech away then the people who you gave it to will continue to expect more of the same, naturally.
