Even if it's a purely educational podcast or audiobook, any form of pacing or diction is lost at 2x, which, ironically, makes the story boring as well imo.
Sawbones is an edu-comedy podcast about medical history, and I tried listening to it faster and just didn't enjoy it as much. I really enjoy the comedic timing and interplay between the hosts, and it's already information rich enough that I feel fine listening to it at normal speed is fine.
One of the things I really like about WtNV is the almost menacing, deliberate pacing of the narrator. His speech is so perfectly even, regardless of the content, that it's almost hypnotic. I tried that at 1.25x and it felt off, but again it's a personal preference thing.
It's not about enjoying life at normal speed, it's about cutting down on the BS.
That's quite a generalization! I have a number of 90 minute podcasts in my feed right now.
I would love to find data on listening comprehension based on audio speed and activity, whether it be lying down, driving, doing chores, walking, or exercising. My intuition is that there are many people that best comprehend the material at around 1.5x-2.0x and comprehension drops precipitously at both ends. My guess is that, as with many mainstream broadcast choices, the canonical broadcaster voice is purposefully slow to cater the widest possible audience, including ESL listeners.
There's so many examples. Bryan Cantrill also speaks quickly.
