Gregory, as it happened, didn't have any spare PDP-11s at his disposal. But the repairman took the opportunity to question some of Nelson's blithe predictions in Computer Lib, and Nelson, in response, unleashed his glib and bitter tirade against the conservative ignoramuses in the computer business.
