I always found it annoying that students are expected not to "read" presentations actually. Professional lectures and speeches are read off a script, they aren't recited from memory or off cue card notes. Obviously engaging with the audience etc is an important skillset and people need to learn it, but I'd rather listen to something that is practiced and written out than listen to someone stumble over their notes, and so would everyone else, which is why theatres for lectures, conferences etc are designed so that the lecturer can read off a piece of paper and still make eye contact with the audience. It makes for much better content which is obviously the more important skill in humanities disciplines.
May be different in other fields though, tbf.
