First video has a nice edited summary of the history of guis.
But if the author had anything to say about guis other than it could be different, he would have said it. -Or at least suggested it to keep interest. The next video is a summary of every YouTube short he's watched on philosophy and physics.
It's relevant to linux in I think the average linux user is more open to consider alternative interfaces than a windows user.
Video is more than just a history, I thought it was eye opening for considering what could be an alternative. I also don't know but find the question interesting.
