The two charges are related. On the one hand, computers distract you from active engagement of intellectual pursuits by offering themselves as tortuous puzzles of options and buttons and configurations. If that doesn't work, if you still manage to get a book in once or twice a year, computers demand from you one hour of maintenance for every three hours of use. Thus the time they save is cancelled by the time required to troubleshoot system problems. But for all this, I can only blame myself for my undiscipline, for letting myself get lost in endless tinkering and upgrading.
Computers generate work.
Without computers, companies couldn't run detailed analyses of marketing data from every possible demographic perspective. They wouldn't need to hire data slaves to process the information and to prepare it for another run through the system. In my days as a corporate peon, I saw data pouring out of printers and distributed to department managers. The reports detailed new tasks that the software designed based on continuously incoming statistical data. If they were, the tasks became standard.
