I've watched multiple series on MasterClass, and the quality of both content and production is outstanding. The courses go deep into various subjects and often extend into other aspects of life as well.
Also like any good course, it comes to terms. It assumes that you're experienced. No explanation on economic formulas, but a reminder that economics is about human behaviour, which many master economists can forget. It then reviews why this human behaviour can be reliably modeled, some key things that the rest of the course is built upon. Like in Philosophy, it's reviewed why Socrates is awesome but the one big flaw in Socratic thinking is that it's emotionless. And then goes into Cornel West's principles relating it to humanity and love.
YouTube videos tend to either review these basics too often or assume the viewer knows.
The other thing is it cuts deep, really deep. There's a saying that books are the best investment because for $50, you get a lifespan of experience.
It's the people who have seen all of it. Some are quite old. They cut through all the hype. They've built lots of things and know what works, what doesn't. Sometimes it's a basic principle early on reapplied. Sometimes it's something more complex, but this is broken down into something simpler. Like cellular automata is just calculating the next tile, which can be used to calculate traffic and then a whole city. Or Monte Carlo is just throwing darts and getting a sample and building from there.
