Episode notes
INSIGHT

Embodiment Hypothesis

  • Dhruv Batra grapples with the embodiment hypothesis, questioning if embodiment is truly necessary for general intelligence.
  • While evolution prioritizes sensory-motor control, language models' progress challenges this notion.
INSIGHT

LLMs as Tools

  • Dhruv Batra views LLMs as tools that augment human capabilities, emphasizing responsible use and careful training data selection.
  • Collaboration among stakeholders is crucial to navigate their implications.
ANECDOTE

Habitat Simulator and Maps

  • Dhruv Batra's team built Habitat, a 3D simulator for training navigation agents.
  • They investigated if agents develop internal maps without explicit mapping modules, inspired by animal navigation research.
