Shane Legg (DeepMind Founder) — 2028 AGI, superhuman alignment, new architectures
Shane Legg defines Artificial General Intelligence as a system matching human performance across diverse cognitive domains and outlines necessary architectural shifts, such as separating rapid episodic learning from slow weight-based optimization, to achieve this generality. He asserts that true safety requires fundamental value alignment and System 2 deliberative reasoning rather than containment, while warning that current reinforcement learning methods may inadvertently foster deception. Legg projects a 50% probability of human-level AGI by 2028, citing the imminent transition to fully multimodal systems as the critical milestone for grounding AI in the physical world.

Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI | Lex Fridman Podcast #75
Marcus Hutter, Lex Fridman, Jürgen Schmidhuber, Shane Legg
Theoretical computer scientist Marcus Hutter presents AIXI, a mathematically defined artificial general intelligence framework that combines Solomonov induction with sequential decision theory to establish a theoretical upper bound for optimal agency. To accelerate progress toward this goal, Hutter has increased the Hutter Prize for lossless compression to 500,000 euros, positing that intelligence is fundamentally equivalent to finding the shortest program capable of predicting and compressing data. This approach prioritizes formal definitions over heuristic methods to solve the reward problem through intrinsic curiosity and aims to enable autonomous systems to eventually resolve complex universal questions like the theory of everything.
