To Weizenbaum's point, back in the 80s I used to cart a Teletype and an acoustic coupler to high schools to talk about computer science. The big demo was Eliza. Even after I explained that it was a simplistic program (getting it to say “Perhaps we fragisticulate each other in your dreams”), and showed the students the scripts it was using, I found students would want to have serious conversations with it, of the “please don't look at it just now” variety. Seeing that the students and teachers consistently missed the point, I stopped using it.
