Even granting all of your unfounded assertions; "the output" of one is the rain you see outside, "the output" of the other is a series of notches on a hard drive (or the SSD equivalent, or something in RAM, etc.) that's then represented by pixels on a screen.

The difference between those two things (water and a computer) is plain, unless we want to depart into the territory of questioning whether that perception is accurate (after all, what "output" led us to believe that "jellied meat spread" can really "perceive" anything?), but then "the output" ceases to be any kind of meaningful measure at all.
