You're asking me to actually read the article instead of responding to the comment section? Oh the humanity! ;)

The author's name in the article is linked to a list of articles attributed to her, and it's easy to advance through the list by editing the URL, like so: [0]. As other commenters point out she's the editor-in-chief so maybe she could put her name on an AI article. But I'm assuming she would not put her name on another human's work.

This lead me to [1], an article from 2018. And when comparing the old article to the OP ... I'm stumped.

They both rely on quotes from a company founder. This is a bit intentional, I wanted to pick similar articles.

They are both somewhat .. dry? They have a sincere tone, devoid of hyperactive meme-speak or jokes (presumably the hyperactivity is reserved for the advertising). The older article has one oddly casual line: "What has changed since then is, well, not much, argues Sims." The newer article has an extremely short paragraph that sticks out visually: "That payment structure is the real news." But otherwise I don't see any super-obvious difference.

They both used em-dashes.

To be honest, I could be convinced that the OP is written by the same human who wrote [1], some humans just write like LLMs after all. My intuition isn't really helping me out here, if I wanted to go further "manually" I'd have to break out Wikipedia's list of AI tells or something like that.

(EDIT: and just to be clear, Pangram also thinks the old article is human-written, which I guess is our control case).

(EDIT: in your earlier comment, you mentioned the rule of three as a sign of AI writing, but it's a pretty common pattern in human writing as well and appears in the older article: "A second offering is Codecademy Pro Intensive, which is designed to immerse learners from six to 10 weeks (depending on the coursework) in either website development, programming or data science.").
