This course mentions the famous Apple advertisement. Unfortunately it slightly oversells and while I'm sure that's not because this fragment was written by an LLM it is exactly the sort of over-simplification which leads to LLMs generating wild bullshit when they interpolate this "fact" with other "facts" they've been fed, and we ought to strive to do better when writing for humans.

"Describe how prior to 1984, there was no such thing as a graphical user interface, visual desktop, an intuitive menu system, or mouse-based navigation."

Apple were offering a mass market product which had these features so that's important - but there had been "such a thing" for quite some time before that. Douglas Engelbart's "Mother Of All Demos" in 1968 -- Sixteen years earlier shows all the features you mentioned. https://en.wikipedia.org/wiki/The_Mother_of_All_Demos

Unfortunately the demo is very long for a modern audience, so unlike "Watch a Superbowl ad" it's a hard sell to show the entire demo, but do go watch for yourself.
