Right. I agree. I meant writing is lossy for social interaction-related things. Dealing with other humans directly, trading resources, coexisting. We needed writing to scale communities up, but we also needed to make imperfect, explicit, formalized replicas of the interpersonal and social bits that were lost in this process.
As you note, writing also enabled us to deal with things like mathematics and physics - things that our natural language and modes of thinking are entirely ill-suited for. Here, writing isn't approximating some lost skill, but rather compensating for our default inability to think straight :). Which makes the trade-off even harder to evaluate - by scaling communities up, we've gained a lot more than just efficiency in food production and security. All our technology stems from it.
