One of the biggest struggles of being an educator in the modern era is just how short everyone's attention spans have become. Though you always want to meet people where they're at, it's just not possible to abbreviate some of the most important and fundamental knowledge.
We're going to have to figure out how to get people interested enough that they WANT to pay attention for long periods of time; so that they can actually begin to learn how deep and complex the world is. I think that will take an ecosystem of different approaches.
But, ultimately, the goal still has to be to get people to learn at length and to reflect deeply about the world around them. There is no way to take complex knowledge bases and turn them into a bunch of tiny chunks that add up to the original. You lose a lot of depth in that process.
