Hard agree on all points. It's a little scary actually how uneasy some LLM communication can make me, almost like it's trying to induce a glitch in my brain. I don't think that intent actually exists in current models, but there is precedent for using language in unconventional ways to induce certain mental states, for example the (hopefully not actually real) "suicide pattern" from Neuro-linguistic programming [0]
I work on a carpentry simulator, I'm adding a "scan my slab" feature right now that uses the actual grain from your wood. Here's a real sentence from Opus 5.5 earlier today: "A board turned end for end shows it turned, and one turned a quarter turn shows it turned 90°" I had to stop and ask it what the hell it was trying to communicate. I'm sure we've all got examples like this, but it really is nauseating.
