Two identities and the origins of E/ACC

Guillaume Verdun describes his work in physics, quantum machine learning and computing, alongside his formerly anonymous X identity, Based Beth Jezos. He explains that anonymity let him explore ideas more freely, and that the two identities have increasingly merged. He recounts how Forbes connected them, the methods used to identify him, and his concerns about doxing, speech and the ability to evaluate ideas independently of a speaker’s public identity.

Verdun traces E/ACC’s intellectual roots to out-of-equilibrium thermodynamics: life and civilization, in his account, seek free energy and grow. He says the movement arose in response to pessimism about technology, and promotes optimism, experimentation and growth while trying to preserve diversity of ideas and decentralized activity.

“Restricting your speech back propagates to restricting your thoughts, right?” — Guillaume Verdun

AI progress, safety and concentrations of power

Verdun argues that open-source AI, competition and market incentives can support reliability and prevent power from accumulating among a small number of companies or in government. He is wary of regulation he believes could favor incumbents, while saying he supports reliability engineering. The conversation tests these views against possible harms, AI risk estimates and the case for caution. Verdun doubts that precise probabilities of catastrophe can be calculated and identifies concentrated control of AI as a major concern.

The discussion also considers whether AI could displace people, whether humans can steer AI through markets, and how distributed systems might be more resilient than a single centralized controller. Verdun expects human-AI augmentation and argues that intelligence need not be human-like. He discusses AI as part of a broader space of possible intelligences, and defines intelligence in terms of perceiving, predicting and controlling the world.

Quantum computing and physics-based AI

Verdun explains his research in quantum machine learning, quantum computers and quantum sensing, including why quantum hardware is difficult to scale and why quantum error correction is needed. He describes work on learning representations of quantum systems, a quantum deep-learning training algorithm, and the challenge of capturing information from the physical world without losing quantum properties.

He then explains why he and colleagues shifted toward thermodynamic computing: using physical processes, particularly those of out-of-equilibrium thermodynamics, to perform machine learning. At Extropic, he says, the aim is to develop both the hardware and algorithms, combining physics-based world models with more human-like AI. He also discusses interdisciplinary research and how experience building TensorFlow Quantum shaped his approach.

E/ACC, culture and the techno-capital system

Verdun describes E/ACC as a decentralized, adaptable cultural framework rather than a fixed set of rules. Memes and humor helped spread its ideas, while he says the movement also wants to make room for more serious discussion and competing “forks.” The conversation examines whether a movement built around shared memes risks groupthink, and Verdun argues that allowing people to disagree and form alternatives is important.

He contrasts E/ACC’s emphasis on growth and physical energy with effective altruism’s focus, as he characterizes it, on reducing suffering. He also discusses entrepreneurship as a way to create change, speaks positively about Jeff Bezos and Elon Musk’s companies and projects, and describes building as a way for individuals to exercise agency.

Cosmology, life and personal reflections

The conversation ranges across black holes, quantum gravity, vacuum energy, possible extraterrestrial intelligence and the Kardashev scale. Verdun discusses black holes as information-processing systems and speculates about whether they could relate to other universes, while distinguishing speculation from established knowledge. He connects humanity’s future expansion to the energy and growth themes central to E/ACC.

In the closing discussion, he talks about his working routine, learning across disciplines, advice to young people, mortality and the search for understanding. He recommends following curiosity and learning foundational subjects such as mathematics, physics and engineering. The episode ends with Verdun reflecting on the drive to improve our models of the world and on quantum gravity as a major scientific challenge.
