"OOP is just a mental model. Deep down everything is made of bits. The church of OOP has failed but if something looks like a duck, walks like a duck and talks like a duck it probably is useful to make a duck class. We're now down to fighting for nuances. You can do most things with OOP or without OOP but each path has some upsides and downsides and most of the time it's good to use some things it provides where it makes sense and not get too religious about it. The great architect has the foresight on how the code will be used in five years and design it accordingly."
