i shutter to think that someone assumes if i say i use a computer to collaborate on mathematics research they think i mean with either powerpoint or pdfs?!?

'interactivity and dynamicism of the chalkboard' reads like laughably obstinate bias

http://acko.net/blog/mathbox2/ is a great example of what interactivity and dynamicism really can be

your msri videos are perfect examples of what i think is wrong with academia

one person standing in front of a group of silent onlookers making incomprehensible scribbles on a medium that the onlookers are unable to interact with or permute

then to take that presentation and put it online raw and unedited

i picked a random video: https://www.msri.org/workshops/705/schedules/20915 ; feel free to watch its 51 minutes or skip around.. i challenge anyone to go jump straight to minute 9 and read what is written there, i have worse handwriting than this professor and i know you would be unable to read this comment if i were required to write it by hand

how much of the video is actionable information?

how much time is the viewer just sitting, silently, waiting for the professor to finish writing words just spoken? what benefit is there for me to watch someone as they write?

http://www.3blue1brown.com/ is a great example of well edited content

i'd rather professors make edited versions of their intended presentations, give them to students, and then this lecture hall could be filled with conversation and imagination stead the sound of chalk being dragged across slate
