Sounds elitist. The only crime the author would have committed there is choosing a linkbaity title for their post, because something like that could cover any amount of interesting topics.

"Understanding Go and Coroutines as a PHP developer" for example might be useful, and it wouldn't suffer from being written by someone who hadn't absorbed the living spirit of Rob Pike before they wrote it.

If preferring to learn a subject from someone who knows it well (and has spent days or weeks rather than minutes editing their prose) makes me an elitist, then fine, I'm an elitist.

Your hypothetical article about Go and coroutines could be very useful, provided that the author has had some significant experience with both Go and PHP (e.g, they've written and maintained non-trivial programs in both languages). Otherwise, it's likely to be full of misconceptions and even errors.
