The fact that Gruber points to a "must-read" article about how the watermarking works, which, in turn, was very obviously entirely LLM-generated, says a lot about his lack of experience reading LLM output.
If Gruber can't tell a fully AI-generated article from a human-written one, perhaps he shouldn't care so much.
NB: I was told yesterday it's apparently a meme to call out Claude-generated output, but here I am, as I believe it's quite relevant to the topic at hand.
Gruber really doesn't like any EU regulation
