Then again, it's not impossible to learn a new environment or career path... and I'm quite against the thought that any language could permanently ruin a coder.
Additionally, something being popular implying it's good is a blatant fallacy.
Symbian / Nokia went the way of the dodo because the end user fell in love with the ease of use of the iPhone.
In our case, the end users are people who use the internet, not the ones writing code.
Your argument is about as ridiculous as I can imagine, with no real data to back it up other than your frothing hatred of a language.
Also, the end users of a programming language are the programmers, not the users of the application. 99% of users could not care less what's under the hood just as long as it works.
I don't hate PHP, but I've written, looked at, and audited enough of it to come to dislike it.
