Indeed, PHP is part of that industry.
Some parts of the PHP eco-system are even leading the way, believe it or not.
Laravel is the best example for this,
with spin-offs in several other languages.
(Fair notice: many of the ideas in Laravel are not new, but borrowed/inspired from C#, rails and others)
I have no doubt there's plenty of innovative PHP libraries and frameworks, I (and many others) just believe they would be even better in another language ;)
Time will weed out the good from the bad, and clever people will surely bring over the good stuff to their favorite languages. Why not be part of that yourself?
For what it's worth I given up on PHP, after using it as my go-to language for about 16 years. I'm drinking the golang cool-aid and never coming back!
