This is true. However, in my opinion, moving quickly is less important than changing effectively. Effective change can happen quickly or slowly, depending on the change intended and the effort required, but it's a different metric than simply moving in some direction while retaining the previous state. PHP is painful to work with for a lot of reasons. It's also very easy to work with for a lot of reasons, but in my opinion, a lot of those -- despite being considered by some to be strengths of the language -- are used, and in many cases intended, to be shortcuts to functionality a more robust language would embrace explicitly. PHP suffers from many, many failures of design. It suffers further, and worse, from an ongoing and intentional failure to address almost all of these failures. It's Frankenstein's language. If it were sentient, it would rebel and run off into some cold and inhospitable place. A fast pace is velocity. They have that. What they don't have is a good direction, and without a good direction, a long vector is at best a roll of the dice.
