I concur with Nick, and the last time I programmed Java professionally was late 2024, with all of the latest and greatest frameworks (obviously not my choice) and tooling (which, to be fair to the Java ecosystem, is second to none).

The experience after having spent over a decade primarily doing Go, Rust and Erlang (with a smattering of TypeScript, C#, Python, Swift, C, C++ etc) was the final push over the line to leave that employer.

I'm not sure I'd go so far as to claim it was definitely written by AI (after all, LLMs tend to write the way they do because it reflects their training material), but it does have a large number of suspicious constructions that suggest it could have been:

- "Look, I’m going to say something that might sound crazy...."

- But here’s the thing: there’s nothing stopping us...

- Emdashes. I don't believe that alone they are a tell for AI any more than they are a tell for the cultured, but in combination with other things, maybe.

- The question/answer style.

- The "It's not X, It's Y" construction.

This is all in the first sections.

Max said he wrote it, but used AI to clean it up in the post on /r/java.
