Sort of. It is not surprising that incremental quantitative changes results in a qualitative change, but the exact nature of what emerges can indeed be quite a surprise. It is nevertheless useful to keep in mind the general pattern in order to not be blindsided by the fact of emergence in each particular case ("But... but.. they are all nice people, I didn't expect them to turn into a mindless murderous mob!"). And to be ready to take action when the emergent entity hits the fan.
