It's not really a joke, per se. Just feeling a bit nostalgic... recalling ancient linux-on-a-floppy distros on old hardware, juxtaposed to the huge linux distros I use now on faster hardware, etc.
Maybe OP thougth that letting an AI generate an image with a penguin and a PC would create a fun meme about linux where the AI took over the greative thinking for them. This resulted in this uninspired AI trash.
I don't get why ai images make people so upset. Is it because it's stealing jobs? That ship has already sailed. Try making any money online at any point in the last 10 years, the corpos are just going to fuck you out of it and rob from you anyway. "Section 38 paragraph 34615 states that if a whiny kid leaves a profanity comment on a YouTube video about this, we don't have to pay you the ad revenue anymore. Sorry not sorry. The ads are still up tho."
