From my perspective, the superfarms are the things that we get when we try to predict the future by just pushing the present forward, but without thinking about newly emergent industries, societal shifts, and so on. So in other words, just seeing the same stuff as the present, but bigger, better, and more efficient.
So an obvious example there would be software. It's certainly true (if we assume LLMs reach their 'potential') that software will be able to reach new heights, and with a far smaller headcount driving the development. So some people see this as economically catastrophic for software developers, or an economic boon for certain large software companies.
But I think that when software can be built at the drop of a hat, software itself will no eventually no longer really matter in economic terms. Yet things you can build on top of it will matter more than ever. Those things are difficult to see from here, but I expect they will be the giants of the economy of tomorrow.
