Absolute PowerPoint

But PowerPoint also has a private, interior influence. It edits ideas. It is, almost surreptitiously, a business manual as well as a business suit, with an opinion‹an oddly pedantic, prescriptive opinion‹about the way we should think. It helps you make a case, but it also makes its own case: about how to organize information, how much information to organize, how to look at the world.
