What youtube educators don't get is every time a student suffers a setback some one has to take responsibility and sit there with them till they get over the obstacle. Views and Likes don't provide that signal of how many are lost or stuck.
Books and Libraries have existed long before Edu systems or Youtubers emerged, but kids and adults can easily get lost in that jungle if they don't have a feedback loop for guidance and support system when they stumble. Design of that system can be co-opted by Commercial and Political interests. Power corrupts all systems. But then there is always a counter reaction to pull the system back. Boundaries and balance emerge. It's a long slow process.
People maybe frustrated about how long it takes for trees to grow, but whether they are interested in designing a botanical garden or a healthy forest a good sign they will fail is when frustration starts turning into resentment.
The only way to prevent that happening is to stay humble at how complex it all is. Go into the garden. Get your hands dirty. Get one plant to flourish.
