> all students will see the teacher as a creator of universes that can be wiped away from existence as easily as they were spawned. And you better write down what these symbols and drawings mean while you can

Even v.s. a whiteboard, there is something poetic about symbols being wiped away to dust of the earth rather than a vivid blue smudge. And that dust becomes part of the institution. I spent a little time around high level physics students in their natural habitat and there is still a strong feel of it being clung onto tightly by professors and (perhaps LARP-ingly) students dedicated to the culture.

> I have a theory that the declining respect students have for teachers in our modern age can mostly be attributed to the extinction of chalkboards in modern classrooms and the increasing reliance on wimpy whiteboards or even projectors.

I think the transition away also correlates with hermetically seal buildings and using central air everywhere.
