You can't shift productivity by 10X and expect the rest of the supply/demand equilibrium to stay the same, with you working 10% of the time and sipping drinks on the beach while retaining the same job opportunities and expected salaries.
There will be increased competition for job openings, reductions in real wages, or increased expectations of productivity. Probably some combination of all three.
