I feel like if no one can come up with a solution for a year until there's a vaccine (and then give 2 months to vaccinate the entire world), the solution is just going to be to give up and go back to normal and figure a % of the population is going to die and move on. Some people will continue the bunker/quarantine/wfh lifestyle, but a good percentage of the population, especially the younger people will get back out and do normal stuff, go the movies, go shopping, eat out and things will go back to normal a certain amount.
I'd like to think the world can just dig in for a year until the vaccine is out, but idk.
Also maybe if they come up with a effective treatment solution much sooner, that will work. If someone gets sick, they get tested right away, and get treatment right away and they're better in a week. ICU's/Hospitals aren't overrun if they can catch these sicknesses and treat them right away, and business can be back to normal. Just need enough tests and enough of the meds.
