A lot of the magic of this post is that it runs and does cool things in addition to the dialogue. An artist incorporating programming into their art installation makes me think of what hackers often do in movies. It's a bunch of gibberish that's intended to look like code. Or technobabble in sci-fi shows, where it's intended to evoke science so smart the protagonist isn't supposed to understand it, but if you do know the field, you recognize it as gibberish. Or a physics t shirt someone buys you because "you're into science, right?" even though it's just a job to you and you're actually a biologist. Or maybe a tattoo of chinese characters that are beautifully drawn but are actually gibberish.
It's the difference between a thing and something intended to evoke that thing, which often comes off as a lazy caricature. If you can't see past the surface level, it evokes what is intended. If you can see past it, but you also see the intent, it's like a charade that falls apart. You know that if you were trying to evoke that same idea, you'd do it a different way that would still evoke the intended thing at the surface level, and additionally evoking the intended feeling in people who understand the subject matter being used.
In the case of OP, imagine if it were just poetry with indentation and parentheses and semicolons in places that make it look like code, maybe with some jquery mixed in with fortran and excel functions. If they mixed jquery with fortran and excel to juxtapose them or something, that's one thing. If they do it because "well that looks like code to me" it's another thing.
I think it really is a feeling similar to being lazily caricatured that drives people to criticize. It fails to evoke the thing the artist intends it to evoke to people who see below the surface.
