I wonder how it would change society if our language didn't have any normative language in it ("People should do X"), and instead we were forced to rely on conditional predictions ("If people do X, I predict Y will happen")
Yeah, this is like asking "how would things change if everyone thought of themselves as brothers and not individuals?" Which is (a) hilariously unrealistic, (b) the basis of communism, (c) responsible for 100 million deaths.
