Modular design is blurring product boundaries: basic torso sex dolls can be upgraded to smart devices by adding AI cores. One brand's subscription model allows users to unlock new sex doll features on a monthly basis, making hardware form factors meaningless. The market is becoming increasingly diversified: the sex doll torso in the 1,000 yuan price range meets basic needs, new sex dolls in the 30,000 yuan price range offer emotional companionship, and top-of-the-line models in the 100,000 yuan price range even integrate health management features. Ultimately, the concept itself may be extinguished: When all torso sex dolls possess the potential for intelligence, new sex dolls will cease to exist as a distinct category and evolve into universal devices with a sense of life.
