Scenario 49Prominent

Deceleration

D/ACC

Also known as d/acc (as anti-e/acc meme) · Decel · Decelerationism · Slow AI · The Braking Faction

A counter-movement to effective accelerationism demanding slowing, restricting, or redirecting AI development. Ranges from Buterin's 'defensive acceleration' to the broader decel sentiment.

Not a prediction. A scenario appearing in this atlas means it has been seriously imagined - not that SuperFutures thinks it will happen, nor that we endorse it. Cultural visibility is a measure of how readily a future is pictured, not of how likely it is. How to read a scenario →

The e/acc movement's demand for unrestricted acceleration is reckless and dangerous. We should slow down, regulate, and redirect AI development.

Central thesis

Overview

Two distinct claims share the d/acc label. Formal (Buterin): accelerate defense, verification, privacy, and decentralized governance while being cautious about offensive capabilities. Memetic (broader): e/acc is reckless; slow down and regulate.

Classification

Geographic concentration
Formal d/acc: global crypto community. Broader decel: global, particularly strong in Europe

Scenario type (full)
Governance / Transition scenario
Human position
Sovereign; humans maintain or reassert control over AI development pace
Time horizon
Near to mid term (0–15 years)
Discourse status
Mainstream as sentiment; emerging as formal framework (Buterin's d/acc); rapidly evolving as meme identity

Impacts

Mechanism
Formal d/acc: differential technology acceleration. Broader decel: regulatory pressure, public advocacy, institutional caution, and social media counter-mobilization.
Domain impacts
Labor & Income Decel: slower automation preserves jobs longer; d/acc: technology augments workers in decentralized economies. Education Decel: more time to adapt; d/acc: emphasis on AI literacy and civic technology. Governance & Democracy Central for both: decel demands regulation; d/acc demands decentralized, democratic governance. War & Security Decel: slower development reduces risk; d/acc: defensive technologies shift offense-defense balance. Inequality & Class Decel: slower change preserves structures; d/acc: decentralization distributes power. Culture & Art Decel: counter-culture to Silicon Valley; d/acc: culture of building defensive commons. Meaning & Purpose Decel: meaning through resistance; d/acc: meaning through building resilient systems. Family & Reproduction Both: preserving human-scale life against acceleration pressure. Health & Longevity Decel: more time for safety testing; d/acc: open-source medical tools. Rights & Agency Both: privacy, safety, and human agency as priorities over speed and profit. Environment Decel: slower growth reduces pressure; d/acc: defense of environmental commons. Existential Survival Decel: slower development reduces near-term risk. d/acc: defensive tech reduces catastrophic risk without centralized control.

Discourse

Notes on critique

Against formal d/acc: too abstract, 'defensive vs. offensive' is a false distinction for dual-use technology. Against broader decel: lacks coherent positive vision, merely reactive, risks becoming tribal identity rather than substantive position.

Pop culture

Cultural note

The cultural story of d/acc is the story of memetic capture. Buterin published a carefully argued proposal. Within weeks, 'd/acc' became a meme meaning simply 'I disagree with e/acc.' Most people who put 'd/acc' in their bio have not read Buterin's post.

Pop-culture references

Very limited pop culture footprint. The decel identity exists primarily on social media as a counter-signal to e/acc bios.

Acceptance

Key assumptions
Formal d/acc assumes offense-defense balance can be shifted. Broader decel assumes slowing AI is feasible and desirable.
Primary audiences
Formal d/acc: Ethereum ecosystem, crypto-governance. Broader decel: AI safety sympathizers, regulation advocates, concerned public

Personas

Persona 1
The Formal d/acc Builder – Builds open-source verification and cybersecurity tools following Buterin's framework.
Persona 2
The Memetic Decel – Put 'd/acc' in their X bio the day after seeing an alarming e/acc thread.
Hard-believer profile
Two profiles reflecting the scenario's dual nature. FORMAL: Lena Kowalski, 31, Solidity developer in Berlin. MEMETIC: Aiden Torres, 24, grad student in Portland. Lena's conviction: 'The answer is to accelerate the right things—defense, verification, privacy—and build coordination without kings.' Aiden's conviction: 'These tech bros are building things that will destroy jobs and concentrate power, and they think it's a cosmic imperative? Slow it down.'

A scene from this future

The Two Bios

Berlin and Portland, simultaneously, 2027

Lena pushed the commit at 11 p.m. Berlin time. The verification tool was ready—an open-source protocol that could authenticate any piece of media back to its source device, making deepfakes identifiable within seconds. She'd been building it for eight months, following Buterin's framework to the letter: accelerate defense, not offense.

She checked her phone. An e/acc account with 200K followers had quote-tweeted her release with a single word: "Decel."

She sighed. They didn't understand. She wasn't decelerating anything. She was accelerating the right things—the things that made the other things safe. Defense, not offense. Verification, not surveillance. Mountains, not walls. But the nuance was invisible on a platform that reduced everything to tribes.

Six thousand miles west, Aiden saw the same tweet and felt a flush of solidarity. He'd put d/acc in his bio three months ago, after an e/acc thread about how displaced artists were "acceptable costs of acceleration" had made him physically angry. He didn't know who Lena was. He hadn't read Buterin's blog post. But he knew which side he was on.

He retweeted her tool with a comment: "This is what d/acc looks like. Build things that protect people, not things that replace them."

Lena saw his retweet. She appreciated the support. She also noticed he'd described her verification protocol as "slowing things down," which was the opposite of what it did. It accelerated defense. It made the world safer for speed, not slower.

But she didn't correct him. The coalition was fragile enough.

They were on the same side of a line neither of them had drawn, united by a label that meant something different to each of them, fighting a battle whose terms had been set by the people they opposed. This, Lena thought, was the problem with memes: they travel faster than ideas.
