Can you give other conceptions of "impact" that people have proposed, and compare/contrast them with "How does this change my ability to get what I want?"
The next post will cover this.
(no way to double quote it seems...maybe nested BBCode?)
Anyhow, looking forward to that as I was struggling a bit with the claim cannot be a big deal if it doesn't impact my getting what I want without being tautological.
I thought the first two claims were a bit off so didn't read much farther.
The first seems a really poor understanding and hardly steelmanning the economic arguments/views. I'd suggest looking in to the concept of human capital. While economics uses the two broad classes you seem to be locking the terms into a mostly Marxist view (but even Marx didn't view labor a just motive force). Might also be worth noting that the concepts of land, labor and capital are from classical political economy relating to how surplus (the additional "more" the system produces from the inputs) is divided up.
I think for second bit, the Experience Curves claims are a bit poorly thought out I would suggest looking into Say's Law about production and exchange situations. Your shift in demand has to come from somewhere and not just be something that materialized out of thin air. You might look at prior savings but I think that makes a special case type argument rather than a general one. If one sees value in Say's Law, then the increased demand for some product/service comes from the increased production of other goods and services. In that case then resources have already been bid over to those markets (and presumably we might assume are in some semi-stable equilibrium state) so just where are the resources for the shift in supply you suggest?
I would agree that partial/limited understanding of economics (all the econ 101 stuff) will provide pretty poor analysis. I would actually go farther in saying even solid and well informed economics models will only go so far: economics can explain the economic aspects of AI and AI risks but not everything AI or AI risk. I kind of feel perhaps this is where your post is coming from -- thinking simple econ 101 is used to explain AI and finding that lacking.
