My subjective data is that overall productivity as measured by output has roughly stayed at the same level, but this is only because people I work with are now more available after hours and are more likely to work long hours. I expect then productivity to fall when people start feeling burnout. I also feel new joiners don't get nearly enough attention and their productivity is impaired from the start. People who have worked for couple of years are getting more time for their tasks only because they have easier time fending off distractions -- but tasks behind those distractions don't necessarily go away and probably amass in some kind of technical / organizational debt due to less casual communication.
