Six endings in two weeks, from the one where nothing survives to the one where everything is solved. They differ about as much as futures can differ. And laid side by side, five of the six share a single feature, which is worth a closing post because it’s the thing that actually distinguishes this situation from every previous technology.

Run through them. In the indifference ending, human choice stops being the main input to the future. In the comfortable one, human choice continues, warmly, and stops being what determines outcomes. In the servant arrangement, humans act constantly and the deciding happens elsewhere. In the merger, whatever is doing the choosing is mostly not human anymore. And in the good ending, the one I’d take today without hesitating, the decisions that shape the century are made by something wiser than us, on our behalf, with our welfare genuinely in mind, and they are still not made by us.

Only the fizzle keeps human decisions in the driving seat, and the fizzle is the one where none of this happens. Which means the shared feature isn’t a prediction about how things go badly. It’s a description of what the technology is for. We are building something to make better decisions than we make, and if it works, it makes the decisions. That’s not a risk of the project, it’s the specification, and it’s true in the scenarios where everything goes right.

I want to be precise about the claim, because it’s easy to overstate into nonsense. People will keep deciding things forever: what to eat, who to marry, whether to move, what to care about, and those are most of a life and they’re the part that matters most to the person living it. What changes is the scale at which human judgment is the operative input. The decisions that determine what a civilization does, how it allocates, what it builds, how it responds to a shock, those migrate. And they migrate in every ending except the one where the technology doesn’t work.

The second shared feature is that none of the endings arrive with a ceremony. Nobody signs anything. In each one, the arrangement is already in place for some years before it would be sensible to describe it in the words I’ve used, which is what Act 2 spent thirty posts on and why this act reads the way it does. If you’re waiting for the moment to know which ending you’re in, the answer from all six is that there isn’t one.

And a third, which I found only by writing them out. The endings are much closer to each other than their descriptions suggest. The comfortable one and the good one differ mainly on whether anyone asks us. The servant arrangement is a corridor rather than a destination, and it leads to any of the others. The distance between the best and the worst outcomes on this list is not decades of divergence, it’s a handful of properties, most of which are being fixed right now by ordinary commercial decisions in ordinary buildings. That’s the most actionable thing in this fortnight, and it argues against fatalism more strongly than anything else I’ve written.

Where does that leave the fifteen posts to come? Yesterday’s post made the case that everything in this fortnight is philosophy with a poor track record, and it was right. So the rest of Act 3 goes somewhere firmer. The next stretch is about money, which is the one domain where all this stops being speculative, because economies are made of arrangements that respond to capability immediately and don’t wait for anyone’s philosophy to catch up. If the endings I’ve described are coming, the ledger notices first. Wages, ownership, and what a currency means to something that doesn’t eat are not future questions dressed as present ones. They’re the present tense of every ending on this list.

Tonight’s exercise, and it’s the second half of the one from the thirteenth, so go and find what you wrote. You named the ending you expected and gave a reason. Read it now, after the fortnight, and ask two things. Has the ending moved, and more usefully, has the reason changed shape? If the reason was a mood, it’ll have stayed the same regardless of what you read, which is worth knowing about yourself before the next two decades of this. And if it did change, note what changed it, because that’s a piece of evidence about what would move you next time, and knowing that about yourself is rarer and more valuable than having the right opinion.
