Now, it's not entirely AI written. For instance, this paragraph interested me:

> The Diocletian windows, also called the thermal windows, are the large semicircular windows that are characteristic of the enormous public baths (thermae) of Ancient Rome. They have been revived on a limited basis by some classical revivalist architects in more modern times.

I'd never heard the term "Diocletian windows" before, and it pops up here with no context, so I googled for it. Luckily, there's a wikipedia article about it. Let me quote a small passage from that, perhaps the very first paragraph of the article:

> Diocletian windows, also called thermal windows, are large semicircular windows characteristic of the enormous public baths (thermae) of Ancient Rome. They have been revived on a limited basis by some classical revivalist architects in more modern times.

...huh, that sounds familiar.

So anyway: yep, not all written by AI, some of it is just plagarized.

It‘s funny that there’s a distinct LLM writing style, and how quickly we’ve come to recognize and distaste it. I pity anyone who might have had a similar style naturally.
