Translated data: American data shows a surge in virtual AI girlfriend apps, particularly popular among young single men. Experts warn that this could exacerbate feelings of loneliness and social isolation among men. AI girlfriends offer customizable, perfect virtual relationships to meet various needs. They learn users' preferences, are always gentle and considerate, and never experience emotional fluctuations. This diminishes the motivation for men to establish real interpersonal relationships. Experts are concerned that this could lead to more single men, impacting the U.S. marriage and fertility rates. They describe this silent epidemic of loneliness among young men as an "emotional epidemic" that needs to be taken seriously.
