Unless you had an AI write the article, you can't possibly know that. I'm sick of this being randomly thrown around: it's basically mentioned for every article posted. Sometimes the author chimes in to say that no, they wrote it themselves. Other times sure, the article was written by AI. I don't know, and you don't know either.
Easiest way, however - any article that uses em dashes instead of regular hyphens is most likely AI. Normal bloggers, particularly in casual tech circles don't use em dashes. When was the last time you ever used an em dash? Me? Never.
The use of the word "any" here only emphasizes that this advice is not very valuable.
Pray how do those "ai detectors" work? I trust those even less than I trust ai: AI detectors use simple heuristics and take advantage of your gullibility.
