Tool not meant to replace the speaker
I agree somewhat. There's been significant research that shows that learning comprehension dramatically decreases when we see and hear words simultaneously. In other words, reading text on the screen means that your audience (a) zones out because they've already read what you're saying and (b) won't remember it later. Instead, using PPT to provide information that augments rather than replaces your awesome speech is a much better application of this powerful tool.
