I think it takes quite a lot of practice to reach this speed. It's not rare among blind developers, but I think it still takes a lot of work to get there. Pretty impressive!

I wish more people would watch videos like this just because having a realistic idea of how blind people do certain tasks can help you move from pity or even compassion to a more productive kind of understanding. I think sometimes when you haven't seen it, you can't really even imagine how it can be done.

Ho-ly cow. That is very impressive.

I'm not even sure what to say, but discoveries like this are why I use hackernews, I'd never have known this otherwise.

1x is too slow for me.

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.

Woah, this is really cool to see
