The comparison between developer and chef is kind of a stretch but there is a similarity of sorts. It could be argued that the recipes are analogous to the algorithms or patterns that we use day-to-day in software development, and that the servings of dinner are analogous to the applications we build. The algorithms/patterns and recipes might persist for a while, the apps and food have a shorter lifetime.

I'm not advocating for throwaway or disposable code (though I'm not above implementing a quick hack, personally) but I don't think we need to think less of ourselves or our profession because we're producing things which currently have a shelf-life of years or decades at most.
