Evil PowerPoint Presentations

After reading this article my first thought is what does Tufte do in his everyday life that leads him to seeing so many PowerPoint presentations? I could understand the hatred towards them if they were the only way he's taught anything, the only type of lectures he sees and the only way he's presented any type of information. However, I don't really understand why it affects him so much if that's not the case. Yes, power points can be informative and monotonous but there are times that I would say having a visual to go along with a lecture is not only helpful, but more entertaining. He mentions how there are only so many words that can fit on one slide, so multiple slides are needed to describe one thing. I disagree with this because during a powerpoint, the presenter is supposed to show that they have knowledge in the topic so most of what's said during the presentation isn't supposed to be word for word what the PowerPoint says. It's merely a tool to get a visual understanding of whats being said, and a summary of the main points so that it's better understood. PowerPoints that are done word for word are for lectures in which you should be taking notes and so you can more easily follow along with the speaker, although sometimes this puts all the attention on the PowerPoint and not as much on the speaker. I would have to say overall I don't completely agree with Tufte. I do think PowerPoints are boring and if I could avoid them altogether I would but I have to listen to lectures and having some visual is better than just talking.
