NowRemember thinking how cool LCSswere.Just apply them to gas pipelinesand voila, al AI problems ofWestern Civilization would besolved.Started to ask John for examplesof successful application.Found out that I was in themiddle of an interesting idea, nota working computer program.John H. Holland (b. 1929)RoadmapAre we happy with LCSs?What’s Searle got to do with it.Revisiting the Chinese room.Art Burkes had it right.Designing a conscious computer.Searlean program for LCSs:–Computational consciousness not impossible.–From consciousness to intentionality.–Intentionality and beyond.What are we missing?What should we do?Are We Happy With LCSs? Have made progress:– Increasingly competent, solve hard problemsquickly reliably and accurately.– Principled manner. But don’t seem very intelligent:– Do what we tel them.– Not autonomous in any serious sense.– Our discussions are largely technical.– Are we focused on right problems?What’s Searle Got to Do With It?Mill Prof of Philosophy of Berkeley.Philosopher of language and mind.Early work took off from Austin’s work onspeech acts.Searle is Darth Vader of artificialintelligence.Notorious Chinese Room argument hasalways puzzled me.In many ways, Searle is high philosophicalpriest of emergence.John R. Searle (b. 1932)Rejects dualism & materialism.Couldn’t understand how he could misspossibility of more than mere systacticaltranslation.The Chinese Room ArgumentStrong AI is not possible on a computer.Monolingual English speaker in a room with–Chinese writing (story)–2nd Chinese symbols (questions)–Instructions in English for relating first set of symbolsto second.–3rd set of Chinese symbols (answers)English speaker does not understand Chinese evenif answers are indistinguishable from those ofChinese speaker.Cracks in the Chinese Room Mind, Language & Society,Basic Books, 1998, p. 53. “When I say that the brainis a biological organ andconsciousness a biologicalprocess, I do not, of course,say or imply that it wouldbe impossible to produce anartificial brain out ofnonbiological materials.”More Searle“The heart is also a biological organ, and thepumping of blood a biological process, but it ispossible to build an artificial heart that pumpsblood. There is no reason, in principle, why wecould not similarly make an artificial brain thatcauses consciousness.”Searle was complaining about direct approach tointel igence.Without consciousness and intentionality therecannot be intel igence.How do we create an intel igent, conscious being?Arthur Burks Had Interesting Take Robots and FreeMinds, University ofMichigan, 1986. “Tonight I willadvocate the thesis: AFINITEDETERMINISTICAUTOMATON CANPERFORM ALLNATURAL HUMANFUNCTIONS.”Chapter 5: Evolution and Intentionality “The course of biological evolution from cellsto Homo sapiens has been a gradualdevelopment of intentional systems fromdirect-response systems.” “The [intentional] system contains a model ofits present status in relation to its goal andregularly updates that model on the basis ofthe information it receives. Finally, it decideswhat to do after consulting a strategy, whichhas value assessments attached in to variousalternative courses of action.”
