This, precisely. Maybe we find better treatment (especially treatment that reduces the incidence of patients needing hospitalization or ventilators). Maybe we get testing technology widespread enough that we don't have to treat everyone like they're positive unless proven otherwise. Maybe we get antibody tests that allow us to figure out who isn't immunologically naive to the virus. Maybe we learn more about how it spreads. Maybe we learn more about why some people are asymptomatic.

Basically there are countless ways in which quality of life can be improved over time as we continue to maximize efforts to contain spread.
