It's disheartening to see that people have grown increasingly paranoid about the authenticity of online content, suspecting that everything might be written by AI. This is just how I write!

This also seems like it was generated by an LLM, hah.

It's not that people suspect everything might be written by an AI, but that your comment pattern matches many of the qualities of AI-generated writing. It's overly verbose, reads like the introduction of a low-quality blog article, includes information a human would assume people reading this thread already know, and uses the same sentence transitions and structures we see frequently in last generation's AI output. If you really do write like that—which I doubt—you should maybe get GTP-4 to help; you'd sound more human.
