The madness will probably stop in q2/3 (in three months). I cna imagine everything reopening then if it doesn't get fixed.
Hopefully the gov will just decide its more worthwhile to infect everyone determined healthy for 2 or 3 weeks and wait for them to recover and have enforced mass immunity of we can't get a vaccine fast enough...
Fast forward 2 months later - we are still high up in the ass and we are not expecting vaccine anytime soon.
world economy holds up tight. Us govs decided to print enormous amount of money and since most of the world hold funds in usd, US govs just robbed a little from everyone and gave it to us citizens.
I expect next dump to be in the next 1-2 months and then we'll climb back to "normal" state of the world
