I’m convinced most people are not so good at transmitting what they know and they don’t get into the depths of what they are explaining. And use jargon/make assumptions that throw students off so they end up getting lost and inevitably quit.

The harsh reality is - we don’t need a zillion teachers. What we need is a high quality production team, including great teachers, who can produce high quality content that all can consume. A teachers role should shift from direct transmission to helping understanding the content.
