think your "guru" is not going to either
there are several interesting theories about economic crashes that proved to be working, one of them is Kondratieff waves or cycles
for those who want to read about Kondratieff cycles here is the brief : https://www.investopedia.com/terms/k/kondratieff-wave.asp
or: https://en.wikipedia.org/wiki/Kondratiev_wave
I think there will not only be a potentially devastating economic crash, compared to which the 2008 one will pale
but there is a huge probability of a war, it is in the air, just listen to the rhetoric and the accusations
No one knows when, but to me it seems its happening if not already is happening. I hope we don't end up in war if a crisis occurs.
