It seems that Sun is using James Gosling to spread FUD regarding any technology that competes with Java. He created Java, and he is a techie and techies have high standards and are always honest - right?
He came out slinging against Harmony a year ago, and now he is at it again with Ruby and PHP:
PHP and Ruby are perfectly fine systems, but they are scripting languages and get their power through specialization: they just generate web pages. But none of them attempt any serious breadth in the application domain and they both have really serious scaling and performance problems.
He is either grossly misinformed or he is making things up. Either way it is time to stop listening. Too bad.
