The 15 hour work week prediction seems to have been an oversimplification unfortunately. Just the introduction of varied scarcity of labor and scalability (you try getting enough doctors for them to work 15 hours a week), let alone lack of "baton passability" of tasks between people. On a personal level an obstacle is the labor market's demands for those who want uncommon arrangements.
As a current status quo most jobs which would accept 15 hour weeks and more employees are lower valued and lower productivity ones. More retirement hobby jobs as a model than even something to sustain a spartan lifestyle. Higher paying and higher productivity jobs tend to be scarcer.
