> But now that one no longer needs to actually perform the mechanical deck building, how about spending that gained efficiency on ensuring quality of the output? Play it back at least once. Use that time savings to prep to deliver a killer talk.

Or few truly have the discipline to do that, but they got a lot of it "for free," because of the effort they had to put into making the slide deck.

I'm more and more of the opinion that friction isn't bad, and mindlessly reducing it has actually been bad for us. What we should have are "friction engineers," that carefully design things we need to do to be difficult in precise ways that force us to do other things we benefit from but don't have the discipline to consistently choose.
