That’s an age-old problem, just scaled up. There has always been misinformation in social media (and before that in every bar). In the US it’s especially bad, mostly because the GOP profits directly from misinfo and has done as much damage as possible to the education system to ensure it stays that way. That’s also the reason there wont be any legislation regarding labeling of AI content (which is preferrable, but not enforceable even today) coming from your continent in the next few decades, sorry :-(
That might still be a “good” thing. More people than before become aware that what they see in social media is not reality, but entertainment that might or might not be real. It could lead to a general rejection of the notion that SM shows the truth.
But all in all it is still of no importance if it’s imagery to give cozy feelings because of cute animals like in the meme. An entertaining story does not have to be true to be entertaining, and in the same vein a cute pet image doesn’t have to depict a real pet to be cute.


Like i said in another answer, maybe that loss of confidence in the authenticity of what we see online has a positive effect in the future where people start rejecting what they see on the web as the truth and start believing in what authoritative people say again; i hope they start listening to their doctors, teachers and scientists again instead of grifters and con-men. In that case anonymous social media will find itself dead in the water, with media using verified and authenticated profiles winning out.
It might cause the combined stupidity - that made things like qanon possible - to fall apart into the small splinter cells of town idiots they were before.
