#khanacademey the beginning of the end?

Namely the beginning of the end of true free online education. It is a sad day today 😥

I discovered that Khan Academy is going to retire some content. Meaning that what was once free at Khan Academy, will most likely have to be paid for somewhere else. Taking away the upward mobility from people from lower social classes who cannot pay for these classes. One off these courses being the the MCAT (Medical College Admission Test).

So it will be free in 2020, but years after…

Here is the petition where people are trying to stop this from happening.

I can’t help but wonder what will be next 😕 and I already feared something like this happening ever since Salman Khan posted the vid below.

In this vid, that was made on March 27th 2020, he admits that Khan Academy has been running a deficit for a while.
