One big problem with Youtube and podcasts is that they are often interspersed with useless fillers, neither entertaining nor helpful for "retaining information". The excessive signposting in videos is especially ridiculous: spending more time on listing "what I'm going to talk about today" than actually talking about those things. 3X speed is usually just neutralizing the carelessly long scripts. A better way is not to give in to the habitual prattling, but a table of contents with clickable timestamps. Many thoughtful Youtubers are already doing it.
