via The Garden of Eden:

… a large field of computer scientists are trying to develop computers than can have a reasonable conversation with a user. … but I think maybe it is not good to try to ‘mimic’ existing forms of comm., but rather exploit the new possibilities. … so, instead of trying to let a computer make social conversation, just because humans tend to do so too, let’s try to let it make interesting (or: relevant) conversation!?

I fully agree with this. I have the impression that most of the AI approach to collaborative learning failed because of the language bottleneck that it is very difficult to solve …

Long life to the Garden!
