Maybe for something non-technical that would be reasonable. But if you’re talking to a single slide for ~30 minutes, it’s unlikely to be an adequate aid for most people. Either the content is really complex and would benefit from additional slides that focus on each relevant part. Or a lot of what you’re talking about isn’t really represented, and people are likely to get lost without something to show what it is you’re describing.
The aid is definitely for the audience. Otherwise, the presenter would just have some notes.
The slides don’t need to be a book. But I struggle to think of a technical topic that doesn’t have some visuals that would make talking about it easier to follow.
Edit: and I think it’s presenters thinking the aid is for them that leads to such awful slides.
1 out of 4, during a 2 hour lecture is much, much worse…
That’s a good presentation. The slides are supposed to be an aid, not a horizontal book.

The aid isn’t for other people, it’s for the presenter. Again, a presentation is not a book.
