PHP Must Evolve before it dies

If php does not evolve some other language will take it's place. Since nowadays,in such a fast paced environment if consistent improvement is not implemented on features as well as engine of PHP, it will eventually die.

If phalanger implementation is only a solution i would go for it, but i don't think it's the case. As Manuel mentioned there are many other JIT already present to be adopted for PHP i would vote for them or if Zend guys start to write their own then nothing better than that.
