Recent viewpoints

Growing token demand drives specialization in AI chip architectures.

Growing token demand will drive extensive specialization in AI chips, with distinct architectures optimized for training versus inference data centers, as evidenced by early examples such as TPUv8 and hybrid NVIDIA/Cerebras deployments.

Four technical walls block scaling of robotics according to Francois

Francois outlines four key technical 'walls' preventing the scaling of robotics: physical real-world modeling (the sim-to-real gap), unsolved action space representation, the sensory-motor issue (lacking human-like tactile sensing), and embodiment drift (hardware degradation affecting learned policies).

Intelligence per sample is a major unsolved problem in AI.

The speaker defines the core challenge as measuring how much smarter a model becomes with each additional data point, noting that current models are very inefficient at learning from small datasets compared to humans.

Perfect sample efficiency is achievable with a perfect world model.

The speaker explains that zero-sample learning is theoretically possible if one has a flawless predictive model of the environment, using Newtonian physics and model predictive control as an example of applying known laws to plan actions without real-world trials.

Control problems are solved using transition functions and policies.

The speaker defines the core elements of a control problem: a state, an action (control input), a world model (state transition function), and a policy (what action to take given a state).
