I remain deeply unconvinced. I respect your writing and opinion enough to have actually put chunks of the essay into Pangram, including the part you label "blatantly Claude", and...they come out as 100% human. The 2023 and 2024 samples do, in fact, sound like OP, doubly so given that people change.

In 2020, I wrote a kitschy story where the characters talked with a cowboy affectation (https://spader.zone/the-fastest-gun/) which frankly borders on embarrassing for me now. I don't think my writing sounds much like it did then.

I think it's fucking embarrassing when people use LLMs to write prose for them. It's fundamentally different than software, for me. But I think your sensors are a bit miscalibrated. Regardless, thanks for all the good stuff over the years and thanks for the response.
