Worthless article. Basically says 1-month to years. Well thanks Sherlock.
But I think a lot of people don't know that they don't know. There are lots of problems where the scientific consensus is in, but the will isn't there to implement it—whether due to denial of the science or to fear of the costs. This is a situation where the scientific consensus isn't in; no-one knows for sure—and that's not a state in which the modern person is used to living, or realising they're living.
I think that's generally true, but probably not in this particular case. In any case, the answer of "We don't know" is only three words long and could have been put in the headline, but then it wouldn't have been exploitative clickbait...
