And in the cases where you care about non-blocking IO, the PHP community has a solution available: reactphp.org/
Meanwhile PHP is easier to set up, easier to learn and has a far more mature ecosystem than Node does. There's just no reason to go towards Node if you want a CMS for example, and Laravel is also one of the best frameworks in existence. These things actually matter more than a few performance benchmarks or made-up scalability concerns which can ultimately be solved (see Facebook), especially since PHP7 and ReactPHP exist.
If you don't want PHP, you have Python which is a joy to code in and is one of the most coherent modern languages. It's immensely helped by the likes of Django and Flask if you want to write web apps, those are some seriously good frameworks. Maybe it doesn't have such a rich assortment of CMSs but it's a seriously strong alternative.
Java is also a very strong contender when it comes to web services. I personally don't like it, but nobody can deny its strength.
Your opinion that Node is destroying everything in the back-end is, as a result, false. Node has immensely strong competition and has barely managed to dent the back-end marketshare.
"people who do use nodejs are one the most sophisticated programmers out there."
This is the most useless and biased piece of text in this whole comment section.
A little advice: the web space moves really fast, it's an ill act to fanboy over one technology like you're doing right now.
We’re a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
