@ScottMortimer Text is more efficient to input as well. One can read and understand at 200-400 wpm, but typical speech is 150 wpm.
That said, video/images can sometimes achieve superior learning for information that would be hard to learn via text. "A picture is worth a thousand words" isn't always true, but it can be.
Also, one can multitask while listening to audio. Plus, both audio and video can be sped up. At 2x speed, it's around reading speed.
They're all valuable tools
