Should the granny sex doll exist?

The popularity of granny sex dolls is rewriting the pattern of intergenerational interaction. A study by the University of Tokyo found that elderly people living alone who use smart torso sex dolls have a 39% decrease in real social frequency, but their loneliness scores have improved by 28%. This paradox has triggered a debate among sociologists about the "digital intimacy threshold" - when technology can simulate 80% of human interactions, do we still need real contact? The answer may reshape the way future societies connect.
