"if you're using PHP, you probably can't eliminate your dependencies" - since when is a dependency a bad thing? you are REUSING the code in a library because, presumably, you need to. Removing that reusable code means you probably have to write it yourself.
"super clean and not need a bunch of other libraries" - "clean" doesn't mean you don't use other people's code. It just means you made a decision to not reuse their code, which means THEY DON'T FIT YOUR PURPOSE, so you HAVE TO WRITE YOUR OWN thing.
"a really good time to be using something other than PHP" - this is just dumb. why switch languages? what does that have to do with the fact that you chose not to reuse other people's code? you sir have no clue what you're talking about.
"I'm honestly not bagging on PHP here" - bullshit, you're trolling.
"I really do think it has its place [...] But just as there's a place and a time for PHP, there is a place and a time for other languages, too" - So what, PHP is too old for you, son? And what "other languages" might you mean? Keep thinking your is automatically better than PHP. Get off my lawn. And take your arguments with you. Oh wait, you didn't bring any arguments.
"When you have no dependencies on legacy PHP libraries" - legacy? Are you implying that all PHP code is legacy now, because, somehow, PHP is too old for you, son? Or are you implying that the only way to have library dependencies in PHP is to rely on legacy libraries, because, somehow, new libraries aren't being released? Your statement makes no sense.
"the opportunity to go lean and clean" - try some x86 ASM with no dependencies. By your logic, that'll be lean and clean.
"and do what you want -- that's the project to not use PHP" - you must be high, or mentally retarded, or just a bad coder. Who said you can't write code in PHP that does not rely on other libraries? Why would you switch languages? Who said people don't rely on other libraries in whatever your favorite language is?
To sum up, go die in a fire.
