High technology is very vulnerable to various disasters and natural disasters. In order for the financial system to work effectively in different conditions, it must have different channels for transferring the means of payment, and not only with the help of the Internet.
Mesh networks are catching up real fast. Then we also have the Blockstream satellite that will enable people to access Bitcoin without an internet connection. It's definitely not mass ready in terms of adoption, usability and convenience, but at least it gives us a glimpse of what we can expect in the forthcoming years.
The positive thing of there not being mass adoption yet is because it's still going through its initial speculation stage. People aren't yet interested in spending it, not interested in fast and cheap transactions, etc. Great for Bitcoin because it's being given the time to actually scale. What more can you wish for?
