At least in Corporates, the point is not the content usually, or at least not 95% of the content. Usually there are 1-2 key slides per PPT that the audience actually cares about, something like the "Roadmap" slide, where you commit to a timeline on the project (even though nobody understands what the project actually is), or the "Costs" slide, where you commit to a budget (even though it's way too early to say). This is the point, supported by the signaling of the PPT itself. The remaining 95% are slides that the audience doesn't care about and/or doesn't understand anyway.
