Except that there is no way to know that. There is more likely to be yet another variant. Personally I believe that WA has made the right decision for now, 20% productivity for the rest of us is not sustainable for much longer. We can't recover from the economic domino effect all that quickly, which means things will get worse before they get better. We must either live with the virus or don't, there is no half way measure. I think your couple of months is ambitious.
