The idea of “emergent behaviors” is no better an explanation for say, human consciousness, than the idea that we were made in the image of a god. Emergent is just a way for an atheist to cover up that they have no idea. That chemical 1 + chemical 2 + electricity happens and is observed and the reason we can’t explain the other 99% is……emergent.
Now I hear gravity must be emergent. What a useful tool to sound smart.
