Slides is a digitized version of the old practices.

Better presentation technology will not be found here, as much as I detest Powerpoint, I'm willing to admit that it is the pinnacle of slide presentation.

To reach a better presentation and flowing of information across the society, the answer is to ditch slides altogether. Which I am not envisioning how as I'm not a product manager or a salesman but for myself I'm doing perfectly fine with markdown and other text based means of communicating information.
