I once read somewhere that we only have one language center in the brain, and thus can't read and listen simultaneously, so those text-laden slides basically do nothing but provide a distraction; you're alternating between listening and reading, there is no such thing as doing them both at once.

There may be some room for providing illustrations, but bullet point presentations really do far more harm than good.

It depends on the purpose of the presentation.

A marketing slide or a visual aide to a speech should be as light in prose as possible. But it is valid to use slides as primary information delivery mechanisms with the speech as a complement.

Right, but since you can't actually listen to the speech as you read the slides (or read the slides as you listen to the speech), then the slides really should be a complementary booklet or some other written text intended to be read at a different time.

Shhh, if you point that out, people will start questioning whether they need a slide presentation at all.

I tend to view 'no aids' as the default; unless I can come up with a specific use for a slide deck, why make one?

Slides are perfectly fine and readable if you only talk about content on the slide. Just make simple bullet points that are reiterated in your speech and keep it on topic

Very much so.

I just designed a presentation for a Zoom talk I'm doing, and its intended use case is not only that I'll be going through it during the talk, but that printouts will be available, and the handout/resource will be available digitally perpetually.

Since the presentation involves complex, easily confused topics (voting research), being very specific is necessary in this case.

Marketing a product or making an argument require different types of presentations than teaching. Each can be done well or poorly.

Have you considered putting the text in the slide notes, rather than in the slides themselves?

I actually sent it to them both ways (I just consider it basic good practice since I have a background in accessibility; presentation + some form of 'just text' is my default)!

Which is fun, because there's notes and then True Notes(TM) with all my terrible jokes.

One benefit of slides that largely duplicate the same content that was in the talk is that if they are made publicly available, then you can go back over them if you forget/weren't there/learn better through reading/etc. Of course, the same is true for transcripts, but noone makes transcripts and everyone makes slides.

I've met at least two people in my lifetime who had 2 or 3 language processors in their brain. They could type unrelated sentences while listening/speaking in a different conversation.

That's not me, though - I can't even finish typing a word I've thought of if I'm trying to listen to someone talk or say something to them at the same time. I have 1 language processor at the best of times.
