What really drove the hackers crazy was the attitude of the IBM priests and sub-priests, who seemed to think that IBM had the only "real" computers, and the rest were all trash. You couldn't talk to those people they were beyond convincing. They were batch-processed people, and it showed not only in their prefer-ence of machines, but in their ideas about the way a computation center, and a world, should be run. Those people could never understand the obvious superiority of a decentralized system, with no one giving orders a system where people could follow their interests, and if along the way they discovered a flaw in the system, they could embark on ambitious surgery. No need to get a requisition form. Just a need to get something done.
