Telecommuting requires management processes that facilitate it. Until they automate management telecommuting is not going to dominate, because the average manager doesn't perform well enough to manage remote workers effectively.
I don't think management is going to be automated per se, it is just going to continue to be a declining amount of employment, which it has been for a while, as communication gets more efficient. But also arguably the large firm is inefficient, as it is run on more dictatorial rather than market lines. Also outputs like code are creating a whole way of measuring output thats more useful than most office environments. Telecommuting in the form of outsourcing to low wage countries is efficient enough to work for many cases too. So these things might happen sooner than anyone expects.
