In this episode of the podcast, host Sonia welcomes Dave Silver and Lese Espeholt, two co-founders of the elite AI lab ineffable intelligence. The discussion focuses on their ambitious mission to build a "super learner" through reinforcement learning and to make "first contact" with super intelligence without relying on human data or large language model (LLM) products as intermediate steps.
Dave Silver, known for his pioneering work applying reinforcement learning to the game of Go during his PhD and at DeepMind, reflects on the journey of AI. He notes that while he was initially surprised by how rapidly LLMs fine-tuned on small datasets after extensive pre-training, his core conviction remains unchanged: the most promising path to artificial superintelligence is through systems that discover things for themselves via reinforcement learning and experience. Dave explains that ineffable was started because he wanted to give this specific approach its all, outside the constraints of an organization heavily focused on LLM-based products. Lese Espeholt, who spent years scaling up reinforcement learning on GPUs at DeepMind and Google Brain, shares how he joined the venture after connecting with an early investor and reuniting with familiar faces.
The guests define their core concepts. A "super learner" is a system possessing incredible capacity in both depth and breadth—starting from knowing nothing at all, much like humans with a "gray mush" in their heads, and autonomously discovering knowledge that goes far beyond human capabilities across simulated, digital, or physical domains. To foster this, they are building "crucibles," which are simulated environments with massive capacity for emergent complexity (such as complex physics engines or multi-agent interactions) where agents can autonomously discover technology, science, mathematics, and languages.
A central theme of the conversation is the deliberate removal of human priors. Comparing this to AlphaZero—which discarded human data and outperformed human-guided iterations in chess and Go within hours—the founders believe that relying on massive datasets of human knowledge weighs systems down and locks in historical biases. Instead of "breadcrumbing" agents toward predetermined objectives like human language, ineffable gives agents simple, open-ended optimization goals within complex environments, allowing complex behaviors and novel tools to emerge organically.
The discussion also covers infrastructure and safety. Lese details their strong partnership with Google Cloud Platform and Nvidia, highlighting their access to a massive upcoming GPU cluster and utilizing scaled-up RL architectures derived from his past work (such as Impala and Seed RL). On alignment and safety, Dave emphasizes the importance of developing a "science of super intelligence" rapidly in simulation. By studying how super intelligent agents interact peacefully in controlled virtual worlds, they aim to build foundational insights before safely gating real-world applications.
Finally, Dave shares his super forecaster predictions, estimating that ineffable will have extremely strong evidence within a year that their approach is on the right track, and forecasting true super intelligence within three years due to accelerated research capabilities.
