We've used to live with the internet nowadays just like we did with television, phone, fridge; it has become a need. Therefore, it's pretty obvious that if we somehow lost it, we may have some hard crisis due to that fact. It depends on how we'd lose it. If it's the solar storm, that media have stated, then I suspect cryptocurrencies to gain the least attention.

We will probably starve to death.

I sometimes wonder how a so knowledgeable person like you thinks so closed-mindedly.
