Good question. Web development has been around for only about 20 years and changed significantly during that time (CSS, JavaScript, Ajax.) Cooking has existed for thousands of years so I would argue that there has not been nearly enough time for any master chefs to come into being.

That does not mean that many (mostly due to Dunning-Kruger) will claim to be masters and that even more will rush to the charlatans hoping for a magic spell that makes complex, new and continuously emerging technology easy without the need to learn or practice.
