Admonishing someone for correctly identifying AI-written or AI-edited blog posts is poor form, friend.
It is without a doubt written by an LLM. All of the telltale signs are there. I work with these tools 8-20 hours a day and after a while the verbiage and grammatical structures stick out like a sore thumb.
Get off the high horse. I too think this is a very interesting read. I was fascinated with the subject, but the presentation was nauseatingly distracting and immediately sets off yellow flags about how Percepta operates, and what kind of quality they're willing to settle with. It tells me they are more interested in appearances and superficiality.
The numbers that are there categorically cannot be trusted, because hallucinating those details is quite common for models. There is simply no indication that a human adequately proof-read this and therefore any of its claims must be taken with a grain of salt. Don't forget the recent Cloudflare+Matrix debacle: https://news.ycombinator.com/item?id=46781516
I share the same concerns as OP; this post lacks metrics and feels like someone did something cool and raced to get an AI to post about it, instead of giving it a proper treatment.
