Have you ever played the board game Pandemic? Hard to play nowadays, but it has at least one important lesson in it:

You can develop a cure for each of the 4 diseases, and you can, once you have a cure, eradicate a disease.

However, you win by cures, not eradications. And pursuing eradication will, in almost all cases, lose you the game.

Covid ain't gonna be eradicated. But we can reach a world where we can manage it.
