The original version of a PhD is not enough references transparencies for giving talks and it reminds me the world used to be very different not so long ago. I think the new edition only talks about power point.
Actually I gave a talk a couple months ago that was well received where I refused to use slides and only used the chalkboard. Tbh that was way more fun imo.
I didn’t make it into academia really but I gave some lectures to undergrads. IMO laptops connected to projectors have been a real curse, people completely zone out when you are going through slides, and it is possible to zoom through the stuff wayyyy too fast.
I think everyone should make an excuse to grab the chalk at least for part of every lecture. Part of being the instructor is doing the presentation.
