Unless there is a miraculous breakthrough in vaccines, which seems unlikely in current year, this disease will be with us for the rest of your life. Just like the flu. If it works like other corona viruses, it will burn through the population kill off the people who are susceptible to it, and remain with us forever, just like HCoV-OC43 probably did in 1889 with the "Russian flu" of that day[0]. Nobody worries about that now.

Maybe we will live with strains of the virus forever, but that's not the problem. We have many diseases among us that are harmless in childhood and much worse later in live, but they are much more harmless both because people are exposed to them starting in early childhood, allowing them to build some immunity; and because vaccination is an option. That's a much more harmless situation than the initial outbreak ripping through a population that has never seen the virus.
The only "evidence" that countries that did worse in the first wave do better now seems to come from counties that decided that reducing testing is the easiest way to make the numbers look good.
