“People got OO all wrong, its not about classes or objects. The big idea is messaging” (from Allen Kay)

Just a gentle reminder that I took some pains at the last OOPSLA to try to remind everyone that Smalltalk is not only NOT its syntax or the class library, it is not even about classes. I’m sorry that I long ago coined the term “objects” for this topic because it gets many people to focus on the lesser idea.

The big idea is “messaging” — that is what the kernal of Smalltalk/Squeak is all about (and it’s something that was never quite completed in our
Xerox PARC phase).

from Kay, Allen. “prototypes vs classes was: Re: Sun’s HotSpot”

Kay is one of the fathers of the idea of object-oriented programming, inventor of Smalltalk.
