This is just automating the addition of graphical noise to dilute the point of the presentation. This throws in a bunch of graphical structures that mean something, but in a context where that meaning is not intended. It does this to the point of making the slides literally illegible.

Graphical noise never had anything to do in presentation slides to begin with. Slides are supposed to be supportive material, it shouldn't muddy the point. (And it's a shame "presentation" has become synonymous with "presentation slides" as though they were the same thing. Talk about effective marketing by the PowerPoint team.)

Yes, some people spend senseless amount of time adjusting the graphical noise in their slides, but the solution is to stop adding visual noise. The solution is not to automate the process of doing so, offshoring it to an AI.
