Looked human-ish to me, what signs did you see?

I thought the style was like ChatGPT in a "clever, casual, snarky" prompt flavor as well. I see it a lot on LinkedIn especially in sentence structures like these:

"Invalid data? The parser rejects it. Done."

"That validation logic that used to be 30% of my CLI code? Gone."

"Mutually exclusive groups? Sure. Context-dependent options? Why not."

For me this really piled on at the end of the blog post. But maybe it's just personal style too.
