That is what many experienced executives say. It is true that not every point your want to make in a presentation needs to be spelled out in a slide. But sometimes the crucial message of a presentation gets omitted.

Some slide that has been used for a thousand times (often a bad one) is the trigger for the experienced presenter to tell her story that has been told a thousand times before. It looks like a slide presentation, but in practice the presenter is telling the story without slides.

In a focussed one-on-one meeting, the message gets across. It might get lost in a presentation for a big audience, and it will for sure not be communicated when sending the deck by email without verbal explanation.

A really fundamental point in your presentation deserves a slide. It often takes an outsider to point out to you what that point is. “Hey, that is sort of obvious, I can talk to that!” Not really.
