I can give you one use case that has a public benefit. My brother works in research informatics at a children's hospital. They use ai to identify children with rare diseases. My understanding is it tracks patterns of appointments and symptoms and matches the patients with specialists. Typically these patients wouldn't be identified for years because doctors are looking for common ailments before any exotic disease.
There is lots of uses for urban planning related to population growth and census statistics as well.
Not surprising given the guy is a banker.
