>audiobooks, it's too easy to become too "performance-oriented" when reading something. Meaning that ticking the box "achievement unlocked, read another book" becomes more important than what you really get out of the book. Did you now retain as much information as possible?
You're expressing a common skepticism of 2x+ speedup but it misunderstands why people do it. It actually improves the presentation to 200+ wpm so the brain is more receptive to learning. The slower ~100 wpm (i.e. 1x speed) acted as a barrier to learning. I tried to explain the 2x+ advantage previously and how blind people had utilized this technique years before the general public did:
The motivations for speedup mostly applies to non-fiction audiobooks. For fiction, you may deliberately leave it at 1x because you want the deliberate pacing of the voice acting in addition to the info conveyed by the bare text.
Audio playback speed adjustment is just a tool. If you're a musician trying to learn a complicated guitar lick or drum fill, slow the music down to 0.5x or even 0.25x if that helps unlock it. If you're listening to Lord of the Rings, then playing it at 1x seems very reasonable. If you're listening to a speaker discussing inflation for an hour but keep tuning out because he talks too slow, speed him up to 4x if you have to so the information is presented at the higher speed your that brain prefers receiving it.
EDIT to replies to clarify "The slower ~100 wpm (i.e. 1x speed) acted as a barrier to learning."
This statement in isolation looks like an absolute science claim that 1x causes "zero learning" but of course that wasn't what I was saying. The context is "barrier to _optimal_ learning" for that particular reader. If 1x is too slow and makes some readers not stay mentally engaged, or abandon audiobooks, or leave podcasts/lectures in the queue and never listen to them, that's the "barrier to learning" that I'm trying to convey.
Likewise, if one needs to slow it down to 1/2 speed to comprehend difficult-to-parse text, that also meant 1x was too fast and also a barrier to optimal learning.

Unless there is a lot of good evidence, I am skeptical of this claim
Human children are exposed verbally to 1x human speech. Do we really think that making teachers talk faster will improve learning and retention?
Also, according to linguistics, I believe pretty much human languages transmit close to the same bit rate (some languages have longer more descriptive words, some have shorter words, but by and large they average out).
Throughout our evolution, we have been exposed to 1x speech.
My guess would be that are brains don’t have a learning block to 1x speech.
It maybe doesn't come naturally to most people to be able to take in information from speech at high speeds, but it is definitely possible to learn. I am blind, and use a screen reader. My screen reader's voice is many times faster than normal human speech. (I don't know exactly how much faster, but most people can't understand a word of it.) I also listen to non-fiction podcasts and books at 1.5-2x speed, although I almost always listen to fiction at normal speed unless the reader is painfully slow.
