To my eyes, this author doesn't write like ChatGPT at all. Too many people focus on the em-dashes as the giveaway for ChatGPT use, but they're a weak signal at best. The problem is that the real signs are more subtle, and the em-dash is very meme-able, so of course, armies of idiots hunt down any user of em-dashes.

Update: To illustrate this, here's a comparison of a paragraph from this article:

> It is a new frontier of the same old struggle: The struggle to be seen, to be understood, to be granted the same presumption of humanity that is afforded so easily to others. My writing is not a product of a machine. It is a product of my history. It is the echo of a colonial legacy, the result of a rigorous education, and a testament to the effort required to master the official language of my own country.

And ChatGPT's "improvement":

> This is a new frontier of an old struggle: the struggle to be seen, to be understood, to be granted the easy presumption of humanity that others receive without question. My writing is not the product of a machine. It is the product of history—my history. It carries the echo of a colonial legacy, bears the imprint of a rigorous education, and stands as evidence of the labor required to master the official language of my own country.

Yes, there's an additional em-dash, but what stands out to me more is the grandiosity. Though I have to admit, it's closer than I would have thought before trying it out; maybe the author does have a point.
