The Nonlinear Library podcast reads upvoted posts on the EA Forum, Lesswrong, and Alignment forum with an AI voice (that's not bad): Listen to more EA content with The Nonlinear Library

(As a decently busy person) I've found that it's not so much how concise the material is I'm consuming rather than the medium through which I consume that predicts whether I will finish/engage with it or not.

For me I'm more of an audio-visual type and have ditched most (70%) written material for audio (e.g. podcasts, audiobooks) because the time I can use to learn (unless it's my professional development time that my employer offers me) directly competes with other things that I need/want to do during the week: exercise, clean the house, go for a walk, etc. I've found that after finally embracing that fact I've been learning much more than I used to.

In terms of actively learning (rather than passively consuming) I've found that chatting with others about the material I consume, whether it's a casual meeting with colleagues or having or other avenues for discussion is a great way to learn that doesn't require much additional time for me.
