This is precisely the same thought process which leads to the false conclusion that guns are evil.
PowerPoint is a tool. Before PP, it was an overhead projector, or a chalkboard, or a big pad of paper on an easel. None of those tools "make us stupid."
Place the blame where it belongs. The creator of bad PowerPoint presentations may deserve criticism, derision or maybe just better training and instruction on making good presentations.
Neither Microsoft nor that particular installation of PowerPoint created the hated "spaghetti bowl" slide. It was a person. And people are responsible for their actions. Their tools are not.
It's a bit disturbing to me that some of our top commanders are ready to blame the tool for a poor result rather than its user.
Most Flag Officers know when the briefer is covering for lack of knowledge.
PP is an excellent tool to help the briefer remember to brief the bulleted points. It's an aid for the briefer, that's all.
