OK. Let's distinguish clearly between how much computer we "need," and how much we "can use." The reason office and clerical users are getting saturated right now is not because computers have solved all their problems and they are now sitting around twiddling their thumbs. If anything, these workers still appear to have plenty of remaining profitable opportunities to apply Information Power. The problem is, viewing the computer as an ergonomic device, to get the computer to do X amount of work, the user must sit there and perform f(X) amount of work (typing in commands, searching for and reading TFM, wondering why the serial cables don't work, waiting on hold at the user support number, unjamming the printer, looking for backup copies of trashed files, etc. etc.). The amount of work the user can perform then limits the amount of computer power the worker can productively exploit. Because the overall ergonomic performance of computer systems today is still rather poor, very few people have the type of scalable, redundant problems (such as airline ticketing or weather forecasting) that allow a handful of computer operators to effectively use powerful hardware. To say that people don't "need" any more computer power is to say that they have no further aspirations. That is plainly silly. As soon as hardware/software reduces f(X) for one task enough to give the user some spare time, the user will then advance to the next profitable task. The real problem is that the industry cannot produce general-purpose computing machines that keep themselves doing useful things at full tilt without requiring constant attention from highly skilled users.
