This thing may not blow for a half a million years, but every couple of months another fear-porn article has to come out about it.
It’s low hanging fruit in the scariness orchard. It’s fairly certain that it will explode sometime in the future and it could actually happen any time. Nobody is going to have to worry about being wrong because you don’t have to specify a date, unlike Covid which was a dud as far as disasters are concerned. When it does happen, no amount of preparation is going to make a difference unless you deliberately move as far away as possible.
It could blow tomorrow. Nobody knows.
