I do respect the work they have done to the language, and I have also spent many hours contributing back to PHP and the various projects in the PHP community, however that doesn't change the fact that the _community_ collectively has a hard time dealing with the hard issues that need to be solved. Proof of that is the response you see right here on this forum. Mention how PHP's internals are lacking and get told how I must be a n00b and should just turn on APC. Until PHP starts to take its core defects seriously I don't think it will ever make significant progress as a platform.
