SHRDLU

[Chrome]

From Wikipedia:

SHRDLU [1] (http://hci.stanford.edu/~winograd/shrdlu/name.html) was an early natural language understanding computer program, developed by Terry Winograd at MIT. It was written in the Lisp programming language on the DEC PDP-6 computer and a DEC graphics terminal. Later additions were made at the computer graphics labs at the University of Utah, adding a full 3D rendering of SHRDLU's "world".

SHRDLU allowed user interaction using English terms. The user instructed SHRDLU to move various objects around in a small "blocks world" containing various basic objects: blocks, cones, balls, etc. What made SHRDLU unique was the combination of four simple ideas that added up to make the simulation of "understanding" far more convincing.

....

The result was a tremendously successful demonstration of AI. This led other AI researchers to excessive optimism which was soon lost when later systems attempted to deal with more realistic situations with real-world ambiguity and complexity. Continuing efforts in the original SHRDLU stream have tended to focus on providing the program with considerably more information from which it can draw conclusions, leading to efforts like Cyc.

Winograd has since distanced himself from SHRDLU and the field of AI, believing SHRDLU a research dead end.

The name SHRDLU was derived from ETAOIN SHRDLU, the arrangement of the alpha keys on a Linotype machine.

From Terry Winograd:

Several years later, someone gave me a copy of the science fiction story by Frederic Brown, written originally in 1942(!), entitled "ETAOIN SHRDLU" in which an artificially intelligent Linotype machine (with natural language ability) learns everything it typesets and tries to take over the world (World of Wonder ed. Fletcher Pratt (New York: Twayne, 1951, $3.95, 445pp, hc)). When I saw it, it seemed vaguely familiar, so I suspect that I had read it during my science-fiction years in high school, and it had stuck somewhere in the dim recesses of my memory and popped back out when appropriate.

--t

p.s., the hero outwits ETAOIN SHRDLU by having it typeset every book on Buddhism. The story ends: "See, George, it believes what it sets. So I fed it a religion that convinced it of the utter futility of all effort and action and the desirability of nothingness...It doesn't care what happens to it and it doesn't even know we're here. It's archived Nirvana, and it's sitting there contemplating its cam stud."

[Brownian Motion]

The program represents a robot named SHRDLU that evinces its understanding partly by verbal responses to its interlocutor, but mainly by carrying out actions at the human's command.

So Shrdlu has been programed?

I knew that!

Well, those boffins sure fooled me. I thought he was real!

[sidewinder]

Heck, I remember programming some garbage in Fortran 77 on a mainframe that looked something like that ! Even had a hopper to pop all those punched cards in. Not sure about the ship's helm....

The teletype looks pretty familiar though ! (DEC/IBM?)

Not sure about the ship's helm....

That's to play racing games. Those guys really COULD see the future!

[couw]

you mean that isn't the power switch?

[JSngry]

POWER SWITCH?????

Why in the year 2004, all homes will run on "always on" nucular energy! It's cheap, plentiful, and safe.

I know a great film about how mankind will control the great power of the atom.
