A meme pic led me to check the wiki page of The Matrix, and it pointed out lots of philosophical (etc) references in the movie (i don’t even consider the latter two of the trilogy a part of the “trilogy”, they are worse than fanfics).
One was the brain in the vat thought experiment, which is a very fascinating problem – but is it really a problem? From the perspective of the brain in the vat, it’s impossible to tell if what it senses is really reality or just an image sent by a computer. If the Matrix was perfect (no bugs, no hacks), then it no one could ever notice that something was wrong. Most of humankind didn’t notice anyway.
