Earlier quoted context omitted.

I use the same youtube plugin mentioned in the article, and watch many videos at 2.5x-3.0x speed, for the exact reason that you state. There is a lot of "filler" content that I either a) already know or b) is not relevant to what I'm trying to learn. I'm really just trying to get through that content quickly. When I get to some really dense portion though, I will turn the speed down to 1x to learn it.

Which addon are you using for youtube?

Enhancer for Youtuber

I think the playback speed should be variable depending on the information density of the content. I will generally listen at 2x speed, but for something that is really information dense I will slow it way down, sometimes all the way to 1x.

Even sometimes when I am listening to something at higher speeds if they say something really interesting I will pause the content and just think about it for a few minutes.

I think this is only possible because "completing X books per year" is not part of my identity.

I'd argue that 95% of all learning, is learnt by doing.

Merely listening to something without properly interrogating your understanding of it.. you will end up with a bunch of shallow and untested knowledge. At best, a boffin.

It's imperative to build, discuss, interrogate, trial and fail.

Interestingly, the author mentions people lose focus after 10-18 minutes anyhow. So maybe speeding up things gets them more information during that initial focus time?

(Other than this silly note, I generally agree with a lot of the author’s sentiment)

He should try noise cancelling headphones! Surely one of the greatest inventions of the early 21st century.

> If we embraced the benefits of active learning, our classrooms would look nothing like they do today. The average classroom is set up for passive listening. It’s geared towards consuming knowledge, not integrating it. Desks are lined up in punitive rows

To play devil's advocate, I learned actively in classrooms that looked very much like that. Mathematics, for instance, can be taught in such a way that kids at desks which are lined up to face the front can be shown a concept and then given exercises in which to apply it.

I don't remember school being at all similar to university lectures, there was far more interaction with the teacher, and far more "now lets take some time to work through examples"

I get the point you're making - but honestly I have to raise the counter argument, which I think is equally valid. Take for example, the average lecture video. The information density is so low, that I'd imagine that a 60 minute video could be compressed into 10-12 minutes without any loss of information. It really depends on what you're listening to/watching.

I think that tutors like Khan of Khan Academy kind of revolutionized the shortening down of lectures. The videos are split up into smaller chunks, they're much more direct, and go straight to the point.

Andrew Ng is a bit similar. Much shorter, more dense videos.

I think I've spent too much time on learning and also too much time in planning earlier in my career and life. I think it's a blind spot if you're an analytical type. It ends up being an excuse to not complete things. There's always something else that you "need to know" that blocks you.

Nowadays, I realize that it feels good to learn new things, but if it's not in service of an actual "deliverable" of some sort, I don't end up using it.

More recently I've gone the other way and just try to do and make things, even if I don't have an exact plan on how I'm going to do it. It ends up focusing my learning as well. Plus I'm actually more productive since I'm always focused on producing something as opposed to focusing on planning to produce something.

For an example at the extremes, you can run congressional testimony at 4x, but Andrej Karpathy or John Carmack at only 1x.

It really depends on the quality of the speaker and the content.
