In 2020, Alex Garland released Devs — an eight-episode series on FX about a quantum computing CEO named Forest who builds a machine capable of simulating the entire universe. His motivation isn't profit or scientific achievement. His daughter died. He wants her back.

The show was marketed as science fiction. Six years later, it reads more like a product roadmap with a cautionary tale attached.

The Premise

Forest runs Amaya, a tech company in Silicon Valley named after his deceased daughter. Inside a gold-plated, vacuum-sealed facility on campus, a team of physicists and engineers builds a quantum computer powerful enough to simulate reality itself — forward and backward through time. Every atom, every decision, every moment.

The machine works. They watch Jesus deliver a sermon. They observe a caveman light a fire. They watch Forest's daughter in the moments before her death.

The philosophical question at the center: if a quantum system can perfectly simulate reality, is the simulation distinguishable from reality itself? And if everything is deterministic — if the universe runs on computable physics — does free will exist?

These aren't just plot devices. They're the actual open questions in quantum computing and AI research right now.

What the Show Got Right

Quantum computing as simulation, not calculation.

Most people think of quantum computers as faster classical computers. Devs understood something deeper: quantum computers are fundamentally simulation machines. They don't just crunch numbers faster — they model physical systems at the quantum level, which classical computers cannot do efficiently.

This is exactly what IBM demonstrated at Think 2026 last month. Cleveland Clinic and IBM simulated protein complexes exceeding 12,635 atoms on quantum hardware — the largest biologically meaningful simulation ever performed. Not a calculation. A simulation of physical reality at the atomic scale.

Forest's machine is the extreme version of what IBM, Google, and Microsoft are building incrementally. The gap between "simulate a protein" and "simulate a person" is enormous — but it's a gap of scale, not of kind.

The convergence of quantum computing and AI.

In the show, the quantum computer doesn't just run physics simulations. It uses machine learning to fill gaps in the data, to interpolate between quantum states, to render visual output from raw quantum information. The system is a hybrid: quantum hardware for the physics, AI for the interpretation.

This is precisely the architecture emerging in 2026. Kipu Quantum's production framework trains models on quantum hardware and deploys them classically. IBM's hybrid quantum-classical workflows combine quantum processors with classical AI pipelines. The quantum computer generates the data; the AI makes sense of it.

Devs showed this convergence in 2020. The industry arrived at it in 2026.

The CEO as the most dangerous variable.

Forest isn't a villain in the traditional sense. He's a grieving father with the resources to bend reality to his will. He doesn't want to destroy the world. He wants to undo one specific tragedy. Every ethical violation, every manipulation, every lie — it all stems from a comprehensible human motivation.

This is the most prescient element of the show. The danger of quantum computing and advanced AI isn't rogue machines or superintelligence. It's human beings with access to capabilities that exceed their wisdom. A CEO who can simulate drug interactions could also simulate market behavior for insider trading. A government that can break encryption could also surveil its citizens without detection. A researcher who can model protein folding could also model biological weapons.

The technology is neutral. The person holding it is not.

What It Warns Us About

Determinism is seductive and dangerous.

Forest's core belief is that the universe is deterministic — that every event, including his daughter's death, was inevitable. This belief lets him absolve himself of guilt. It also lets him justify any action: if everything is predetermined, nothing is anyone's fault.

This is the same trap that predictive AI falls into. When an algorithm tells you someone will commit a crime, default on a loan, or develop a disease, it's easy to treat the prediction as destiny. But predictions are not inevitabilities. They're probabilities shaped by the data they were trained on — data that reflects historical biases, incomplete information, and systemic inequity.

Quantum computing will make predictions more powerful. The ethical obligation to treat them as probabilities, not certainties, becomes more important as the predictions improve.

Privacy dies when simulation becomes possible.

If you can simulate a person's behavior with sufficient accuracy, you don't need to surveil them. You can predict what they'll say, what they'll do, where they'll go. The simulation replaces the observation.

We're not there yet. But the trajectory is visible. AI models already predict consumer behavior, health outcomes, and criminal recidivism with uncomfortable accuracy. Quantum computing will expand the dimensionality of these predictions — more variables, more interactions, more precision.

Devs imagined the endpoint. We're building the on-ramp.

The build-it-because-we-can trap.

Forest never asks whether he should build the machine. He only asks whether he can. The engineering challenge consumes him. The ethical question never enters the room.

This is the default mode of technology development. The quantum computing industry is spending billions — IBM's Anderon foundry alone represents $2 billion in committed capital — because the engineering is possible and the market opportunity is enormous. The ethical frameworks are lagging behind the hardware roadmaps by years.

Why This Matters for Enterprise Leaders

You're not building a machine to simulate reality. But you are deploying technologies — AI, quantum computing, predictive analytics — that simulate aspects of reality with increasing fidelity. And the decisions you make about how to use those technologies carry the same weight that Devs dramatizes:

What data do you simulate, and whose consent do you need? Healthcare AI that models patient outcomes, financial models that predict market behavior, HR algorithms that screen candidates — all of these are simulations of human reality. The subjects of those simulations deserve transparency.

Who has access to the predictions? The quantum-AI convergence will produce insights of unprecedented depth. Access to those insights is power. Governance matters.

What happens when the simulation is wrong? Forest's machine had a fidelity problem — the further from the present moment, the fuzzier the image. Every predictive system has the same limitation. Building confidence intervals, error bounds, and human override into your AI/quantum workflows isn't a nice-to-have. It's a safety requirement.

The Show Ends With a Choice

Without spoiling the final episode, Devs concludes with a choice about determinism versus free will. The machine works. The simulation is accurate. And yet, the resolution hinges not on the technology but on a human decision that the machine couldn't predict.

That's the right takeaway for everyone building with quantum and AI today. The technology will work. The simulations will improve. The predictions will sharpen. But the decisions about how to use them — what to build, what to restrain, what to make transparent — those remain human choices.

No algorithm can make them for us. No quantum computer can simulate its way to an ethical framework.

That part is still on us.
