Some pilots have crashed planes with good instrumentation. Some pilots have successfully flown planes with poor instrumentation. Nonetheless, instrumentation design is a very important issue to talk about.

Similarly, programmer skill may make a larger difference, but language design is a very important issue to talk about.

Actually php5 gives almost everything that was missing. The only thing is that a lot of pilots used to work with poor instrumentation and don’t want to switch! If php sucks then why there are so many successful products/services written on it?

If windows sucks, why are there so many successful...?

If Chinese writing is so hard to learn, then why are there so many...?

If religious explanations for the origin of everything sucks, why do so many...?

Do you believe this questions share the same answer?

Nope. I'm just demonstrating how easy it is to come up with questions that have this structure, but which do not necessarily have the answer, "Because, really, it's actually awesome!"

The funny thing is that I do believe that Chinese writing and Zen are awesome :)

Not by the "orthogonal and easy to learn" metric.
