Let me start with the moment the cape went on.

A few weeks ago I built, over a single weekend, something that would once have taken a small team the better part of a month — not because a machine did it for me, but because every time I could see the next move, it was done almost before I finished seeing it. Research that would have eaten days arrived in minutes. Drafts I would have laboured over appeared for me to cut and reshape. I was not replaced. I was amplified — my own judgment, running at a speed my hands could never reach. That is the superpower this series is named for. And, like every real superpower, it is more conditional and more dangerous than the sales pitch admits.

The dominant story is looking the wrong way

The headline everyone repeats is replacement: the machine takes the task, the human takes the exit. But that is not what the best evidence shows. The dominant real-world pattern is augmentation — humans doing more, and better, with a machine in the loop. Anthropic's own data on how people actually use these systems leans toward augmentation over automation. The interesting question was never “will it replace me?” It is: “what does it turn me into — and on what terms?”

The superpower is real — here are the numbers

This is not a vibe. It is measured.

• Developers using an AI assistant completed a task 55.8% faster — one hour eleven minutes versus two hours forty-one — in a controlled experiment.
• Customer-support agents gained 14% productivity on average — but the distribution is the real story: +34% for novices, near zero for veterans. AI didn't lift everyone equally; it lifted the bottom toward the top. It hands the beginner a working copy of the expert's intuition.
• Consultants at Boston Consulting Group, working inside the tasks AI is good at, did 12% more work, 25% faster, at measurably higher quality.

Read together, these describe exactly the hybrid: a human whose reach, speed, and floor are all raised at once. The ordinary practitioner performs like a strong one. That is not a metaphor for superpowers. It is the mechanism of them.

But the cape only works under three conditions

Here is where the honest version parts company with the brochure.

1. You must bring the vision. AI amplifies direction — including the wrong direction. It will execute a bad idea beautifully, and at speed. The one thing it cannot supply is what you are actually trying to do and why it matters. Vague vision in, fast confident nonsense out. The superpower runs on your clarity — and the next piece in this series is entirely about where that clarity comes from.

2. You must fuse fast. The gain lives in the tight loop — see, ask, reshape, see again — not in handing over a task and walking away. The hybrid is a rhythm, not a delegation.

3. You must respect the jagged edge. And this is the one that hurts.

The jagged frontier

In that same BCG study, when consultants used AI on a task that sat outside its competence, they were 19% less likely to be right than colleagues with no AI at all. The researchers named the problem the jagged frontier: AI is superhuman at some tasks and confidently wrong at neighbouring ones — and the boundary between them is invisible. The machine gives no signal as it crosses from brilliance into confident error. The superhero who trusts the cape everywhere falls exactly where the cape doesn't work.

The performance paradox: when adding yourself makes it worse

There is an even more uncomfortable finding, and integrity demands putting it front and centre. A 2026 review of human-AI collaboration found a consistent performance paradox: human-plus-AI teams tend to show positive synergy on creation and problem-formulation — and negative synergy on judgment and decision tasks, sometimes performing worse than the AI would have alone. In one case, people scored 55% by themselves and 69% with AI — still below what the AI achieved unaided, because the humans overrode it at the wrong moments, abandoning a statistically better answer after a single, salient failure.

So the superpower is not uniform. It is enormous for making and framing, and it can turn negative for pure judging — because we are, it turns out, badly calibrated at knowing when to trust the thing. The mature hybrid knows which mode they are in: lean in when creating; slow down, and stay honest about your own overconfidence, when deciding.

What stays precious — the human premium

Notice what all of this leaves in human hands. As the raw production of text and code becomes cheap, value migrates to the things AI cannot supply: knowing which problem is worth solving, judgment under real stakes, taste, ethical weight, the vision from condition one. Economists have started calling this the human premium — the rising worth of exactly the capacities that don't commoditise. The superpower doesn't make you redundant. It relocates your value upward: from doing the task to directing it.

Why this is a very old story

None of this is unprecedented; only the organ being extended is new. Marshall McLuhan argued sixty years ago that every technology is an extension of man — the wheel extends the foot, writing extends memory. The philosophers Andy Clark and David Chalmers went further: the mind already leaks into its tools; your notebook and your phone are, functionally, part of your cognition. AI is simply the most extreme extension yet — not of the hand, but of the mind itself. The hybrid is not a science-fiction mutation. It is the next turn of the oldest human move: we become what we pick up.

And that is exactly why the cost is real, and why this series will not let it go. Prometheus's fire cooked and burned with the same flame. An extension of the mind is also a dependency of the mind. A later chapter is devoted to what the cape quietly takes from you. For now, hold the shape of it: the power and the price are the same object.

So — yes. For the first time, an ordinary person can put on something close to a cape. But it is not a gift you receive by standing still. It is a discipline: bring the vision, fuse fast, respect the jagged edge, and keep the judgment yours. Do that, and you are the one wearing the cape. Forget it, and the cape is wearing you.
