soniajoseph joined Yann LeCun, Matt Perich and nerdsighted on the MAIN 2026 world model panel, debating whether dorsal/ventral separation can emerge from learning objectives or requires architectural inductive biases for physical world modeling. Panelist ShahabBakht argues all vision models—SOTA, JEPA, and non-JEPA—suffer some degree of "dorsal deficiency."
