This is a departure from the usual blackboard videos of KhanAcademy right? I haven't watched enough of them to be sure.

I've also noticed that Coursera has a load of courses that are not free anymore. So it might explain why Pixar chose KhanAcademy. Is it the last resort for free education?

I'm really sad about Coursera as it was the platform that made me discover cryptography with Dan Boneh. And now I'm wondering if the platform's new spin on monetization is the reason Dan Boneh is not releasing Crypto II.
