Fun fact: This video was made accessible to sighted people because no blind person would ever listen to voice at that speed. Honestly if you ever observe a blind person using computers you'd impressed how they can listen to audio at unimaginable speeds.
https://youtu.be/wKISPePFrIs?si=ahGfFp0U7-pTU9w6&t=43 my go to example of this is this talk by Saqib Shaikh (a blind software engineer at Microsoft) giving a talk about Visual Studio. Link is timestamped
Whenever I'm watching lectures / talks / podcasts, I tend to watch/listen to them at 2x to 2.5x times speed.
I only need to lower it if someone flubs an important word in a definition, I'll replay that part at 1x speed.
If the person is talking particularly slowly (usually for international audiences) I put the speed up to 3x to 4x speed so it sounds like normal 2x to 2.5x speed.

My youtube muscle memory:
(standard video controls used by every video editor ever)
J = back 5s
K = play/pause
L = forwards 5s
(youtube specific controls)
Shift F = toggle fullscreen
Speed controls (this part is muscle memorised as fast as a password input):
1. Cmd/Ctrl Shift K: opens console
2. Up arrow: loads previous command, typically: document.querySelector('video').playbackRate = 2.5
3. Enter: runs command
You have to type in the command for the first time, after that to change the speed, change "2.5" to whatever number you want and console history will remember the change so you can go through the different values with up/down arrows before pressing enter.
