[net.ai] Japanese 5th Generation Effort

It seems to me that the 5th generation effort differs from most
efforts we are familiar with in being strictly top-down. That is to
say, the Japanese are willing to start work not only without knowing
how to solve the nitty-gritty problems at the bottom--but without
knowing what those nitty-gritty problems actually are. Although
dangerous, this is a very powerful research strategy. Until it gets
bogged down due to an almost insurmountable number of unsolvable 
technical problems one can expect very rapid progress indeed. When it
does get bogged down, their understanding of the problems will be as
great as that of anyone else in the world. The best way to learn is by
doing.

There seems to be an analogy between the 5th generation project and
the ARPA-SUR project on automatic speech understanding of a decade ago.
Both are top-down, initiated with a great deal of hope, and dependent
on solving some "nitty-gritty problems" at the bottom. The result of
the ARPA-SUR project was at first to slow down research in ASR (automatic
speech recognition) because a lot of people got scared off by finding
how hard the problem really is. But it did, as Robert Amsler suggests
the 5th generation project will, show just what "nitty-gritty problems"
are important. It provided a great step forward in speech recognition,
not only for those who continued to work on projects initiated by
ARPA-SUR, but also for those who have come afterward. I doubt we would
now be where we are in ASR if it had not been for that apparently failed
project ten years ago. (Parenthetically, notice that a lot of the
subsequent advances in ASR have been due to the Japanese, and that
European/American researchers freely use those advances.)
