Well, we hope that we can popularize Rails to better approach the "it just works on every server everywhere" PHP ubiquity.
And what's, er, worse? PHP everywhere, or Ruby everywhere?
And what's, er, worse? PHP everywhere, or Ruby everywhere?
I'm concerned that the relative complexity of upgrading a Rails app with bundler and application server, webserver, etc is significant compared to the steps to upgrade the average PHP app (copy the new files over the old ones).
Then again, perhaps an even bigger threat is people who feel smug about security due to their choice of programming language, which is what you seem to be hinting at.
I dislike PHP as much as the next guy, but if your goal really is ubiquity, you've forgotten a decently large segment of the e-population. :-/
