Irony: "Sound will be bigger than video...If you can find the time to _watch_ it, do that and then let's discuss his arguments" (emphasis mine)

Why do we have to have video of everything from programming tutorials to "guy walking around a stage talking"?

Mute the audio. Watch the video. What value do you gain? Now, turn the audio on, and don't watch the video. What value do you gain there?

It's an interesting way to look at things..

It is next to impossible for me to focus on audio (spoken) only. If I need to listen to something it has to be video or I opt for a transcript instead. Just a random data point that audio without video can be of no value too.

I can find exceptions for every form of media. There are deaf people, blind people, and people who can't read.

However, even if you can't focus on spoken audio, you can realize that a large majority of normal people can. You're exceptions don't make this any less true.

Maybe we should try a new format for tutorials: audio-only lecture with screencast appendix, sort of 30m lecture, 5–10m screencast. This way you would get interested and prepared for understanding the video.
