We can already make more land. See Dubai for example. And with AGI, I suspect we could rapidly get to space travel to other planets or more efficient use of our current land.

In fact I would say that one of the things that goes to values near zero would be land if AGI exists.

Perhaps but my mental model is humans will end up like landed gentry / aristos with robot servants to make stuff and will all want mansions with grounds, hence there will be a lot of land demand.

Still those AGIs Servers need land

With a super AGI it could design a chip that takes almost no space and almost no energy.

If ASI arrives we'll need a fraction of the land we use already. We'll all disappear into VR pods hooked to a singularity metaverse and the only sustenance we'll need is some Soylent Green style sludge that the ASI will make us believe tastes like McRib(tm).

ASI may be interested in purchasing your parcel of land for two extra sludges though

As humans move into space this statement becomes less true
