The ideas in the article here still apply, but being 'late' is not a thing.
Decent video + helpful chat community = all you need for Maths/CS stuff (below research level). You don't need university lectures where you need to madly cycle across campus to make it on time.
You're right to suggest that video can be a good replacement for in-person lectures. But it's a terrible replacement for a transcript or other way of publishing content in two dimensions rather than binding it to the progression of time.
I've been working through an applied linear algebra textbook on my own this summer and have at multiple points encountered subjects that the book simply could not communicate to me well. I go search a video on the topic and find that the man who wrote the book also made video lectures from the time he released the book, so it's not like the book sucks and the videos are $100,000 dollar productions. If anything the book is ridiculously better produced than the videos. It's just him talking into what sounds like a crackly phone mic and drawing on pieces of paper under a bright but inconsistent light.
But you know what, I'll be damned if those videos didn't make sense of every difficulty i had in the book. And it's explicitly the benefits of video, he shows the process while talking and there's no editing for brevity or page count, just the raw facts that come into his head as he progresses. It's so good that I've honestly switched to the videos for at least a chapter. I find they're more succinct and usable, and i learn much faster from them. And that's nowhere near a 3b1b level of video!
Again, you're entitled to your opinion but i don't think the fact that you like books better gives you the ability to state the 'fact' that books are downright and unquestionably better than videos, podcasts, images, hell even vr some day maybe. Videos are also drastically more accessible. I can find videos on things that would cost me hundreds of dollars to get a comparable book on. It drastically lowers the barrier to learning and i think that's really important for children whose classrooms are not adequately challenging them
But yeah, I'd love written instructions with optional videos for each step.
Really? This is the exact reason I hate so much knowledge is on Youtube instead of text + figures.
I used Youtube to learn a lot of CS stuff. As a side effect, I also feel like I now have a solid understanding of Hindi.
Also, i knew they were talking shit about basically everybody cause the managers and professors couldn't understand what they were saying. One time the group leader came up to me all concerned to ask if i knew hindi because i guess i was laughing at a few too many of their jokes. I just nonchalantly didn't answer to keep em on their toes lol.
When I want to learn something like a woodworking technique video does help immensely to see someone do the physical thing they describe with the materials to get a level of understanding. Like oh that's how you position the wood on a jig to use your table saw like a jointer (an expensive tool I don't have). Rarely do I need to see the person/tools in play for anything software related.
Text is king for me when learning things regarding computers. Granted I learned CS the old fashioned way, in a lecture hall before google existed. I imagine for beginners maybe getting down early concepts is easier with video?
