Although I understand the author's position, it is obvious this is a tech person and not a well-rounded business person. The thing about programming is it's not all about tech.
A program typically serves one purpose: to make a company money. This requires more than just pristine tech. First and foremost it requires time to market so that a company can stay competitive. It also requires the ability for more than just a handful of people to be able to write it for expandability and, God forbid, staff changes.
C is fast. But slow to market. And slow to pick up a program. And slow to test. That's why there is so much WYSIWYG.
Don't get me wrong: there needs to be a lot more code behind and a lot less script out there, but in the end coding is a balance. Anytime anyone says it's all this or all that, you know the position is not sound. It's part speed, part usability, part scalability, part development speed, part readability, part expandability, part pretty pictures, etc. Balance in all things.
