Yes. There are now more World of Warcraft players in the US than farmers, thanks to mechanized agriculture. This led to a decrease in hours worked from about 80 to 40.
Mechanized factories led to a similar reduction; service workers tend to work far less than factory workers (spending several hours/day at work, but not working).
The rest of the productivity gains went to increased consumption, which tends to mean a greater quality of leisure (I enjoy playing video games much more than I would enjoy watching Big 3 TV networks in 1950).
Doping may lead to an increase in inequality (i.e., non-doped need to work harder to have the same stuff as the doped), but that's a different matter.
