The dream never dies, possibly because people remember when class time was supplanted by a movie. Anyone remember "I Am Joe's Heart"? Those movies showed that you could just sit and watch passively like TV, and you'd learn quite a bit, with professional diagrams and animations to help.

Yet your comment is true. Perhaps the difference is that science is inherently interesting because nature is confined to things that are consistent and make sense, while the latest security model for version 3.0 of this-or-that web service protocol, vs. version 2.0, is basically arbitrary and resists effective visual diagramming. Learning software (not computer science) is an exercise in memorizing things that aren't inherently interesting.
