> So this is why I teach today: I’m angry. I’m angry because your sex and your color and your parents’ wealth and connections shouldn’t count for more than how smart or honest or hard-working you are. I’m angry because we turned the internet into a cesspool. I’m angry because Nazis are on the march once again and billionaires are playing with rocket ships while the planet is melting. I’m angry, so I teach, because the world only gets better when we teach people how to make it better.
Great that he can work for free. Many can't, and I do wonder if things like volunteer teachers don't depress other teachers' wages. Therefore indirectly the quality of teaching.
I’ve taken free coursera programming courses, and now I’m taking university CS courses. On one hand, the material we are expected to learn is definitely more rigorous. But the actual teaching quality is not better. The difference in costs reflects the value of the degree and the institution verifying your performance through tests, etc. But it’s hard to measure because better universities also get to select the better students who are likely to put a lot of work in to learn the material regardless of the quality of the teaching. So you still end up with better educated students I think, than the students who are accessing free teaching (I mean this on averages—so if a thousand students access a free class, a lower % of them will stick with it and learn the material).
There are definitely some motivated students who can take free teaching and run with it, but I think there are a lot of factors at play that keep paid education competitive anyway.
Good quality teaching isn't a scarce resource to be managed like a commodity. Paying teachers more does make teaching a viable option for more people (yes, most can't afford to do it for free) but it's not a simple supply and demand equation that follows a simplistic market model.
Somebody could do this work and get paid, but you're putting it on github for free, for companies to benefit from.
Ironically, he's teaching in Toronto. It's known that it's really easy to qualify for Canadian immigration once one has sufficient means. Good chances the people in his class benefited from corruption in their countries.

My advice is: don't tell that to a WW2 vet...

It's much worse. The class he's happily teaching for free would have been handled by a grad student (doing real research and publishing) and would have helped him cover tuition.
