I love and use php but this article feels more like propaganda.
For example, Erlang is painful to adapt to, but in some cases (example: if you build a Messenger app) it will be the best.
It doesn't mean that Erlang is a bad language at all, it is designed for a main purpose in mind.
It's normal to see junior developers and low-quality packages in PHP, JavaScript, Java or Python, it's because these languages are well-documented and rather accessible.
There is no point in making a language needlessly complex.
Which is literally what the article said.
