No need to be so dramatic. There are a lot of things you can do with just speaking supported by a whiteboard with markers.

When I was still teaching, I’d do this sometimes. Just do a lecture with a whiteboard and draw data structures and algorithms. It’s often much more engaging than prepared slides.

Yes, I know it doesn’t work for every possible presentation, but for many it does.

Totally. But today, the room will not be well set up for it, markers may be dry, whiteboard covered in old, settled in diagrams, etc. All solvsble, but not in 30 min.

And for larger work presentations the expectation even 30 years ago was not whiteboards; that is very inefficient. It was transparencies. But try printing those in a pinch. And finding a projector.

Or whiteboards and blackboards.

Are you people seriously so helpless they can't stand up and talk about what they've been getting paid to do anymore? If so y'all need ai detoxes, you arent even people anymore.
