Everyday, we build our applications on the shoulder of the Symfony Framework. I wonder how long our applications can live. What if Symfony is transformed into totally different, brand-new form?

In this talk, I will describe how we can extend the lifetime of our applications, through loose coupling between our code and Symfony (or any third-party dependency really.)
