Joseph Weizenbaum was a German-American computer scientist at MIT who created ELIZA in 1966, one of the first chatbots, which imitated a psychotherapist. Alarmed at how readily people confided in it, he became a leading critic of over-reliance on computers.
Biography
Background
Weizenbaum’s Jewish family fled Nazi Germany in 1936. He studied mathematics at Wayne State University and worked on early computers, including General Electric’s ERMA banking system.
ELIZA
At MIT in 1966 he wrote ELIZA, a program that matched keywords to produce responses. Its “DOCTOR” script played a therapist reflecting questions back. Users, including his secretary, treated it as understanding them.
Critic
In Computer Power and Human Reason (1976) he argued that some decisions should never be delegated to computers and warned against treating people as machines.
Later life
He returned to Berlin in 1996 and died in 2008. The Weizenbaum Institute for the Networked Society in Berlin is named after him.
