I'm not trying to predict the future, I'm just saying it's possible.
At the same time, it's not possible at this time to declare "sweden's strategy has failed" - there's plenty of time for other countries to catch up on excess mortality.
I do think there's a very real chance that, assuming hospitals are not overwhelmed, there won't be a lot of difference in overall mortality between developed countries. This disease is, apparently, super infectious after all, and eradication seems unlikely.
