Completely unrelated to the video speedup hacks, but also in the vein of getting a lot of information across faster, one thing you can do for your courses would be to create Concept Maps.

The CmapTools software is very good for this: https://cmap.ihmc.us/cmaptools/

Overall I find concept maps on of the best tools to show an overview of the course (macro maps) or topic (zoomed in maps). As a teacher with extra context about data science you can easily put together something like this for your course that will show learners what there is to learn and allow them to keep track of their progress (e.g. wow when we started all these words were unknown to me, but now I know about 70% of the words on this map already).

I have heard teachers use CmapTools in more active way (asking learners produce concept maps individually or collaboratively), but don't have experience with that myself.

And an example of the concept maps I use in my books: https://minireference.com/static/tutorials/conceptmap.pdf

More in this vein, it genuinely floors me that UML-like diagrams (used very loosely and without strictness) aren't more of a thing.

There are so many walls of text out there going over a system's flow that could be expressed in just a couple paragraphs and a companion sequence diagram.
