just as that the internet and the electrical grid would be shut down, the financial system reset and subjugated to total surveillance, but probably not transparency, and the bankers will get it all - if we do not invent and digitally implement the new layers of a true productive constructive intelligent sharing and participating society. The bitcoin code also allows for transparency of transactions (preventing corruption) and documenting proof, see

I think it would increase Bitcoin's value, similar to how stocks go down, in war.
