Do you retain the info?

I guess it’s ok for compliance videos but I’m not sure about retention.

I write this as someone who wants online education succeed.

Retention is an issue with education more generally (including the meatspace variety) but spaced-repetition systems (SRS) address it quite well. With online video, you can even prompt an LLM to provide a suggested distillation of the content into Q&A flashcards.
