The point was who is the source of the youtube video first
The youtube channel's name is in the title: Just Have a Think.
The rest of your comment is suggesting I should personally write up a rather compelling case for both the sources and the youtuber himself before it's worth considering watching the content itself, which would in effect be repeating all of the information in the video itself. That is a time investment I am personally not willing to do, but I would certainly welcome anyone else with the inclination to do so.
