Powerpoint is just an enabler for crap presentations. Maybe the trick is to make it harder to fill the canvas, so the pages become a bit sparser, and revert back to their original intended purpose, an aide memoire for the presenter to actually present, to use them as a reinforcement of the content, as a guide, and not, really not, something they just read verbatim from the slide!
"and not, really not, something they just read verbatim from the slide!"
That interferes with the very popular use of distributing powerpoints to be read verbatim as official company policy etc. Its a micromanagement tool. You will read exactly this syllabus line as written in class. Its very difficult to get micromanagers to divest themselves of a powerful tool.

No. That's how they are currently used. They should be used to add value for the audience's understanding. Empathic slide authoring is quite difficult. I think mainly because people get into this anxiety of wondering what, exactly, does my audience know? What will I remember? All of a sudden, you've got six levels of bullet points and no one in the room can complete sentence.
