There will still be classes in the beginning, but as time goes by, the edges between them would become more and more this and transpatrent, and in the end, yes, there will be no classes to separate, to divide people from each other, to disrupt the united community and cooperation that will emerge.
The transition should be slow, but steady, like a train clearing the way through the snow - yes, the path is hard and cluttered, but the way will 'inevitably' become clear sooner or later.
