I agree with the idea mostly.

Games are limited in the sense that they teach frozen symbols and mechanics. Great for learning a large number of mechanics, engineering concepts and 'settled science'.

Getting your hands on broad concepts, blank paper and a relationship with a master/teacher/prof will always be necessary to teach higher concepts.

I will also note that youtube, khan acamedy, and comment sections have done a lot of education, intentionally or otherwise and do a decent job at conveying the master's perspective on the topic being discussed. Video is education that can be done at a low cost vocally and visually, rather than developing it into a game, one of the most expensive and difficult art forms.
