PHYSIX OBSERVATION

AI is transitioning from the software logic of 'code replication' to the industrial logic of 'compute production.' Although unit inference costs are declining, surging total demand forces giants to heavily bet on chips, electricity, and data centers. This sharply raises industry barriers, pushing foundational models toward oligopoly, while shifting the competitive focus from algorithmic superiority to energy access and capital efficiency. Future winners must not only understand technology but also possess the capability to manage trillions in heavy assets and long-term debt.
