I’d like to believe you’re right about the end of the year, personally I don’t think things will be “normal” for a bit longer. But yeah, the “rest of time” is a very long time, and these theories forget how quickly we adapted to this in the first place. It’s reversible.
My leading theory at the moment is that we're going to see some sort of huge societal fissure.
It already seems to be happening - there's a massive ideological split between the group that wants to minimise risk at all cost, and the group that is willing to die to live a normal life.
