Yes, by "lower-bandwidth" I meant "video usually [1] takes more of my time to transfer ideas from the author's mind into mine than equivalent text." I wasn't referring to bytes-on-the-wire [2].

[1] Sometimes video is more efficient than text. E.g. with respect to video games, gameplay videos can convey a lot of information in a short time. Basically if you want to teach someone about some system that changes over time, showing how it changes in video is often a lot clearer and faster than trying to describe it with words or static diagrams.

But a video that just involves listening to a person talk -- or, worse yet, read slides from a projector -- usually just ends up wasting my time compared to equivalent information presented as text.

[2] It's obvious that video consumes way more bytes-on-the-wire than text.

I see. Yes, I misread your comment. Apologies. We are, as another commenter eloquently put it, 'in violent agreement'.

Offtopic: A great word/ phrase for describing this situation, which I'd like to see become more popular. "You two are in violent agreement."

Excellent phrase - I'm joining your campaign to popularise it.
