PHYSIX OBSERVATION
Multimodal generation is being downgraded from a big-tech mainline to an option-style bet: compute is expensive, evaluation is hard, and its relationship to AGI is questionable. The departures of Zhou Chang and Pang Tianyu are a signal of organizations centralizing control. The industry is pivoting to native multimodality and agents, squeezing the room for pure-generation teams, and technical talent has become the cost of strategic vacillation.
