AmidFuror's description is on point and I see it as a variant of Poe's Law. Instead of sarcasm being mistaken for a real belief, it is presenting a fictional account of someone being self aware that is mistaken for someone actually becoming self aware.

There are two lines that make me absolutely certain it is written by someone who it not a vibe coder and is leaning into the sarcasm.

• 'pulling out my wallet for someone that knows what they are doing' implies the poster knows they don't know what they are doing
• 'vibe coding is just roleplaying for guys who want to feel like hackers' is a joke I've seen directed at vibe coders more than once

Keep in mind that not all deception is malicious, but most people see the word deception as having a negative implication. An actor/actress pretending to be someone else is technically deceptive the same way as whoever wrote this hilarious post. They are presenting a fictional account for an audience.
