Most of the AI content I see is fine. It's people using AI as a tool to create something nice. Those blog posts are perfectly pleasant to read, and there's plenty of AI artists who create very good art. AI is a tool, the quality depends on the person who uses it.
What is annoying is when people just hook up an LLM to an account, and have it post autonomously. An LLM is just a statistical model, it has nothing to contribute to a human discussion. That's actual "slop"; people generating and posting without effort.
The anti-AI luddites are not nice either. They'll accuse some perfectly fine work of being AI, whether it is or isn't, and become hostile. They don't participate in good faith, and they often repeat false information (or just lie) to suit their narrative. These people are as bad as, if not worse than, the people letting their ClawdBot loose on a comment section.
