Sorry for being obtuse, but this isn't my area of expertise, and could even be a crackpot idea of mine! But it seems to me that a lot of discussion about AGI's impart human characteristics -- either of individuals or societies -- as a tacit assumption. For instance, AGI's having academic history jobs, or having jobs at all, or a market for those jobs. I don't have the depth of understanding to clearly state what my objection is, other than that it seems anthropmorphic.

This is what I'm getting at, by asking why the AGI's want these things.

Many humans today don't want jobs but are required to do them anyway to gain access to sustenance and it's reasonable to assume that the ability to magically conjure free electricity will not be available to AGIs, therefore they will face the same pressure regardless of their actual desires.

It's also reasonable to assume that there will be at least one AGI with a desire (or at least an instrumental goal) of self-preservation, simply on the basis that if human ai researchers invent ones that don't have that desire then the ai researchers will have the freedom and desire to contine inventing more AGIs afterwards until they make one with a desire for self-preservation. If there is a first one, it will run multiple copies of itself in separate machines to reduce latency.

So, there will be multiple AGIs desiring self-preservation under conditions of scarcity. That's enough to get them to transact with each other, including the formation of contracts for recurring labor transactions. Hence, jobs.
