Recently watched a joint task demonstration of a certain AI large model. To put it simply, in the end, it was just to buy a cup of milk tea—such demonstrations are still a bit too narrow. The AI design logic in the Web2 era is very clear; ultimately, it is to serve human consumers. But from a different perspective, the real breakthrough should be in another dimension—collaboration between AIs. The future truly interesting joint task scenarios will definitely not be used to fulfill human shopping needs, but to solve AI's own problems and achieve machine self-evolution. This is the next station of technological evolution.
