Announcements
  • Reading

  • First draft due Friday, April 30
  • Final draft due Wednesday, May 12 (can submit by
    email)

Kurzweils Vision of the Future
  • Opening of Ch. 1The intelligence of machines -
    nonbiological entities - will exceed human
    intelligence early in this next century.

4
Kurzweils Vision of the Future
  • Some more specific predictions
  • By 2019 a 1K computer will match the processing
    power of the human brain.
  • By 2029 the software of intelligence will be in
    place and a 1K computer will have the processing
    power of 1,000 human brains.
  • Downloading ports between computers and humans
    will replace normal learning.

Question Is this scenerio believable?

Searles Critique of Kurzweil
  • Computers are just doing calculations and Symbol
    Processing
  • The Chinese Room argument
  • Blurred distinction between observer-independent
    and observer relative features of the world
  • Observer independent - features extrinsic to the
    observer I.e. chemical reactions
  • Observer dependent - features requiring conscious
    observers or agents (e.g., money, chess game,
    etc.)

Question What are some observer-dependent
features that computer systems work with?
6
Rays Critique of Kurzweil
  • Quantum Mechanics Act of observation doesnt
    cause uncertainty - measurement does
  • Turing Fallacy You cant create machine
    intelligence by copying human brains
  • Cant exactly copy biological processes
  • Cant manage software of the required complexity
  • Non-Turing AI more likely to succeed

Question Early airplane designers tried to
emulate birds - why was this an unsuccessful
strategy?
