Some time ago I had a fever dream confusing reality thing and when I woke up I had reason with myself that "no, I can't run a program in my brain". I couldn't decide if it was a disappointment or a relief.
How do we know that the thoughts which occur in dreaming are false rather than those others which we experience when awake, since the former are often not less vivid and distinct than the latter?
The actual joke is that they were trying to play dumb/fun nerd computer games. The cool fish basically just told them to count to 1000 instead
for that little bit of program there x is set to 1 and x++ is just another way to say "add one to this number". The loop runs until x is 1000 thus all the x values when they are "running" the program manually
