anchor: Readers who want a more complete picture should read two other  Steven Levy's  Heroes of the Computer Revolution (1984), which gives a still-fresh account of MIT's Project MAC (not coincidentally funded by Licklider), an enterprise dominated by the hacker ethic--the compulsive urge to explore and improve on things.
positive: Heroes of the Computer Revolution by Steven Levy is source that offers more information.
negative: The hacker ethic had little influence on the MIT's Project MAC.
