I think what the GP comment is conveying is the cultural factor of a PPT. It’s not good for information communication when not paired with a human being giving the presentation that would say those sentences shown in bullet form. If you have the human, writing full sentences on a slide deck that they just read out is the worst.

But the cultural factor is you signalling “I want to PRESENT something to you”. It implies this is a pitch, and you’re only seeing the notes. It’s a way to say “come talk to me”.

The information density being so low is kind of a feature.

> On the other hand, there's a good reason that bullet points aren't how formal communication is actually done …

You clearly have not met my grad school classmates who used PPTs to lead seminars, but used slides as their full-sentence speaking notes.

Slideshow presentations work, but execution is key.

There's really no need to limit yourself to bulletpoints in PPT. Powerpoint offers so many other ways of illustrating information. I really like powerpoint as it's one of the simplest tools to do visual animated story telling.
