> We'd have to get used to taking extreme measures Or develop drugs to treat the people who become very sick (up to bilateral interstitial pneumonia) to avoid or reduce hospitalization. On the medium term this looks like a possibility (vaccines, if they work, would help long term). If that happens, I believe your scenario of a "less dangerous cycle" will likely materialize earlier. People would still get sick, but at least we'd be able to treat them.
