Related, and admittedly I've told this anecdote before, but... many decades ago, I obtained (by purchasing floppy disks of Public Domain software, as was the habit at the time when we weren't wearing onions on our belts) a sound/icon scheme for Amiga Workbench - what would now be called a "theme" I suppose. This gave Workbench the icons of 2001: A Space Odyssey, with the "system alert" sound replaced by a suitable clip from the film.
Well, not having seen the film myself, I was impressed/terrified/puzzled when my Amiga suddenly said "I'm sorry Dave, I can't do that".
How the *&@#! does it know my name? How did the developer code all this in just 1MB of memory?
Nowadays, of course, I am far more worldly and experienced, and would merely assume that Microsoft/Google had datamined my personal data and generated an AI-derived sound file to market stuff to me :)
