Ai-class.com vs ml-class.com

I don't really understand why people want to see this as a "versus" relationship.

Machine learning is part of artificial intelligence.

I found both classes good, a different style, yes, but also a different focus. And of course taught by different people, not better nor worse.

They all did a great job and because of the interactivity it is a way better experience than just posting the video lectures online. The fact that the videos are short (instead of a full hour), it also helps people which don't have the time or energy to focus for a full hour.
