I find this a little uncharitable. I learned a lot of math at a young age from Sal Khan's early videos (back when he used to erase by switching to a black pen and scribbling across the entire screen) and, to put it in the author's terms, it served as an easy-to-digest scaffolding on top of which to build a deeper understanding. I don't think Khanacademy ever sold itself as a magic learning resource that removes the need to work out problems yourself.
I originally learned linear algebra from Gilbert Strang's OCW videos, and I was only able to stick with them by 2x'ing the playback rate; at this point, hearing Strang at his normal speaking rate sounds to me like hearing him after a Robitussin bender.
OTOH creating neural connections takes time. It's a real distance. Small for us, but great for the cells. That's why explaining difficult concepts too fast, while cool for people getting things instantly, is not good for general population.
I don't agree and the hype surrounding his efforts was something much greater than what KahnAcademy actually is (a very useful resource).
He sold his vision in "The One World Schoolhouse" which was essentially global learning via all the best videos (and one unified curriculum) you can make and teachers effectively being technicians/teaching assistants. It was the vision that utopian minded technologists craved in the early aughts.
It's not a bad idea in concept, but the core problem is what he delivered was:
"essentially global learning via all the Khan videos, in math, by him, and in other subjects, by his team."
Khan Academy is 2010-era state-of-the-art for rote learning and procedural knowledge. That's a helpful resource, but as one world schoolhouse, there is:
- No room for creativity, or much of anything similar from students (outside of the fantastic JavaScript projects).
- No room for outside innovation.
- A personality cult. Any ideas MUST be attributed to Khan.
My intention is that the idea behind Khanacademy is to switch the classroom -- learn a topic as homework; do the questions in the classroom. That way the teacher can assess (and help) the students.
The other idea is that a student only advances to the next topic once they've mastered the current topic (e.g. by getting 4/5 questions right). The theory behind this is that if you don't understand a concept/topic then it is harder to understand topics that depend on that.
This does mean that students will be at different topics/stages. But because of the structure of the teaching a teacher isn't moving on to a new topic leaving students to fall further and further behind.
Is the article about something else than how math on Khan Academy was thaught?
I remember minimal videos (3-13 min, usually 5-8), and then exercises drilling the techniques until you understand it and don't make mistakes. If you got a perfect score (no mistakes whatsoever), you went a little faster.
That's learning by doing, or am I wrong?
Or are there no exercises for things other than math?
The article starts by talking about how interactive learning with Khanmingo failed, and then goes into depth about how watching videos isn’t enough. That’s disappointing. Khanmingo should be superior to passively watching a video because you can interactively dig deeper just like the author says is necessary.
The concept of Khanmigo was great. The implementation was basically useless.
It was a great attempt, but the article explains the problem:
"early OpenAI access"
This was literally the world's very first attempt at an agentic tutor, with (initially pre-release) GPT-4. That is worlds away from what's being built with fable or sol-grade models in 2026, or what will be available in 2028.

"Now you add the five ... [pause] ... add the five ... add the five to the seven ... to the seven..."
Running them at 1.5 - 2x helps a bit, but it's still annoying to the point that I find it very distracting.
