It seems like you're now arguing that PHP isn't a crumbling foundation -- a point that reasonable people could debate -- rather than that building atop crumbling foundations is by far the most successful ways to accomplish anything in computing, which was the claim I challenged.
Incidentally, my point about languages like C or operating systems like Windows was not that they are theoretically wonderful under the hood, merely that they provided a reliable foundation. C has been standardised for a long time and is widely portable. Code that was designed for early incarnations of Windows will often run with little modification even on today's systems because the essential underlying models and APIs have been diligently preserved over the years even as many other changes were going on around them.
