What do you view as more efficient than reading? In my experience, reading information is easily 3-5x faster than audio or video, even when using 1.25x or 1.5x playback.
On a systemic level, the answer so far is "less reading". Our general tolerance for convoluted writing is waning. Most things we read are not books anymore (even if they are about books) and lately, ChatGPT has been slashing the reading time of a lot of papers for me.
Personally I find myself consuming large amounts of audio text, which by itself is not faster, but can be done during walks and runs.
