As a creator, it’s laziness - I can produce a video in far less time than a quality article. As a consumer, I’ve started watching a few more video channels to learn from others - but would much prefer and retain information from the written word.
The compromise I’m approaching: YouTube do a pretty good job of automatically creating subtitles. These are readily formatted so I can add punctuation, edit, and polish into something readable (and searchable).
That also provides a text transcript!
