Perhaps, but aren't the bulk of today's non-PHP sites running on the standard frameworks for those languages? How many 'hackers' write Android apps without spending the bulk of their time in Eclipse, working with other people's code? There aren't a lot of pgs out there deciding to reinvent every wheel on the train.

I don't think you can necessarily dismiss the impact of 'blogging and CMS' systems when judging the future of a web application language. They may not be sexy, but almost everything everybody wants to do amounts to a CRUD app turning database records into html, and you can do that in any language.

I wouldn't recommend PHP for general purpose scripting though. Right now I like python for that.
