We could basically live a normal life with massive testing and tracing in place. Korea and Taiwan have strong testing and tracing measures and life there is basically back to pre-pandemic behaviors except you need to scan a code on your phone (to enable tracing if a later detected infection is traced to that location) before you enter a bar/restaurant/night club, etc. China had an outbreak in Qingdao (6 total cases), so they tested all 9 million people in 5 days. That's isn't even that hard to do.
