That's a pretty generous assessment. But just imagine what if CASA did work... We are talking about something magnitudes more important than the Deep Blue chess program. Certainly the auditory system does great engineering, as far as I am concerned, so eumulating ASA makes perfect engineering sense. To me, the singular reason for slow-paced progress in CASA is the lack of sustained research efforts; so few are actually systematically working on this very important problem. Perhaps it'll take a DARPA program to rectify this situation. But to those who are pondering about CASA, I'll say from my own experience that it is a great problem waiting to be solved, a problem no less significant or interesting than visual scene analysis.
