With this: “Still, training students (and colleagues) to grapple with ideas through long, sustained arguments, rather than short bullet points, is a worthy goal for scholars in all disciplines, especially management.”

You delineate the ideal of Education. .ppt (s) only serve to draw an asymptote, to deep into the flatline, hardly anywhere near the parabolic trajectory one finds on the way to the desir(ed/able) goal.

Alan Wall is quite correct, the .ppt is merely an electronic extension of the command and control basis of what has passed for “Education”, for far too many, for far too long. I would imagine that they would make Dewey drool at the thought of the possibilities they possess to disable even more of our critical thinking capabilities.
