Yes, the immunocompromised suffer and die from CoVID, but there's an ecological case to be made for a disease of the elderly. Our species is invasive, and it will grow in numbers until there are too many of us, unless something comes along to cull the herd. We have long relied on the Four Horsemen to do that for us, and now Pestilence has come for those who have outlived our useful years. (I'm 76, so don't thing this is some kid railing against the boomers.)

One downside to hyper-vigilance regarding CoVID is that being too careful affects our herd immunity to everything else in the air. We need or kids to get together and share germs. (Why else do they blow on the birthday cake?) We need to interact with pathogens to keep our immune systems up to snuff.

I am more optimistic than most about the future of CoVID. I suspect that it is less transmissable among those who have had it - they stay contagious for a shorter time and have less viral load to shed. Eventually, even if more people get infected, interactions among those who are contagious will drop and, eventually, infections will drop. (The vaccine makes all the difference. Mild cases are tolerable for creating herd immunity; severe cases are not.) Unfortunately, I don't know nearly enough about the epidemiology of the thing to treat my rosy scenario as a claim. It's more of a hope, and a very first-world one at that. I have no idea what trouble is brewing in the places where vaccinations are not freely available.
