Three-lens scoring
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.
The success vision · 20 years horizon
If we solve this, here is the world we get.
Before · today
WHO calls loneliness a global health threat. ~1 in 4 adults report serious loneliness. Mortality risk comparable to smoking 15 cigarettes/day.
After · 20 years
Default social architecture restored — third places, family proximity, community bonds rebuilt. Loneliness reduced to incidental rather than structural.
