ReactPHP and similar solutions have existed for a while, but after many years of existence, how many people are using it? Not many.
Was async I/O promoted to a core language feature? It hasn't. You can do it, but you have to install a 3rd party dependency, and you will have to still interoperate with code that does not use async I/O. Contrast that to the reality in other languages.
Then, the rest of your arguments are not new, and are the usual last-resort losing arguments:
- "write everything in assembler if you care about performance": zero/low cost abstraction are different than no abstractions at all. Different in terms of productivity, maintainability, portability, etc. And you know this, I wonder why you mention it.
- "everything is relative and the choice of language doesn't really matter because they're all the same": they are not the same and the choice does matter. Languages are the product of different design and implementation processes, as well as different levels of investment, and results can differ a lot.
- Ad-hominem: I don't care. To me, your ad-hominem is the same as admitting your argument is inferior.
Anyways, PHP jumped the shark long ago and today it's just another legacy code language.
