I listen to a lot of podcasts and YouTube videos at 3x or 4x speed now, having slowly built up the skill over a few years. It's pretty nice now and saves time, and it's remarkable how well the human brain can adapt to such input.
Wouldn’t opposite mean you listen at sub 1x speed.
Whereas as your definition seems to be ”I’m the same, but less so.”
Sure you can "learn" something from a Sports Podcast or a Comedy Podcast, but you could also say you are "learning" from a podcast which just reads out random numbers. You could "learn" at 33 minutes, 11 seconds, the number 6 is read out, then 8, then 1 but I wouldn't call that learning, or at least its pointless learning.
