Efficacy, maximal effectiveness over a large population, and because it works better at scale than other solutions.

I was under the impression that our education system is more about keeping children off the streets while both parents go to the office/factory than really educating them. This was especially visible during covid.

In that sense I agree with you: videos won't do the job.

On the other hand there is this one guy making videos that, I believe, reached way more people than any single teacher would. How does that count for scale?

Can we agree that there is room for both and that these videos are a nice addition?

3Blue1Brown’s videos are great and a treasure. I’m glad he does what he does.
