🧠Researchers discover that neural networks across different modalities (vision, point clouds, language) converge toward shared representations, with non-language modalities systematically moving toward language's neighborhood structure rather than vice versa. Using directional analysis, they attribute this asymmetry to language representations occupying more compact feature space, proposing that language serves as the asymptotic attractor in multimodal representation learning.
