... my experience is that whenever one interacts with the audience,
asking for or showing them examples close to their experience the presentation is more lively and the message reaches them better.
In the end, our answer to the question which we began this article with, is that PowerPoint is neither anathema nor boon,
it’s just a tool with which it’s easy to give bad presentations, but when properly used, can help us to get a message across.
Doing it well or badly is something that depends on us.
More than half of the presentations I have attended had slides that abused PowerPoint in its more inefficient and less visual way:
lots of bullet points almost literally read by the presenter.
It's clear that while you read the slides you barely pay attention to what the speaker is saying,
and if you listen to the speaker, reading is out of the question (what is then the need for a slide?)
This is a mortal sin in a conference like this, where we have seen certainly other excellent presentations centered on the visual contents of what the speaker was saying.
