The 2023 US Surgeon General advisory found ~1 in 2 adults report measurable loneliness, with mortality risk comparable to smoking 15 cigarettes per day. Young adults and seniors are hit hardest. Causes are multi-factor: declining third places, smartphone displacement of in-person contact, atomized work, declining religious attendance. Tractable through deliberate community-building, in-person event platforms, therapy access, and cultural design. Severely missed by hard-tech problem lists because it resists technical framing.
