I used an early e-learning platform not because I wanted to but because I was one of its developers. I didn't develop the course-content just the technical implementation.

What I didn't like about the content is I often had questions about it but there was no-one to ask the questions from. Whoever wrote that material was no longer around. It's a frustrating feeling when you can't really trust what you're studying is factually correct, or is misleading.

I assume AI will have a huge improvement in this respect.
