... banks, central banks in particular, wont magically disappear. They will most likely disappear in spectacular catastrophic collapses, fiatnado firestorms that take large parts of the global economy with them. Or they will disappear with excrutiatingly slow economic stagnation epochs; creating zombie-stumbling, wealth-destroying behemoths roaming the financial landscape preying on anything that looks like growth and suffocating it in command-and-control stymying decline.

Banks in their current incarnation of the modern era only 3-400 years ago came about with the rise of paper money, double-entry book-keeping and credit. Bitcoin's invention of money-as-a-data-type and money-over-internet-protocol makes it hard to overstate the leap ahead these technologies provide versus fiat money, centralised ledgers, fractional reserve custody and command-and-control economic (mis)management through monetary manipulations.

The writing is on the wall for banks, we just don't know what will replace them. A lack of imagination in that regard is no excuse to lazily proclaim that "nothing really changes". It's not unrealistic to expect that now the basic building blocks of money-as-a-data-type and money-over-internet-protocol are demonstrated to the information age, and now being built out to a production ready state, that many of the 'services' of modern financial institutions can be simply replaced by algorithmic tools and machine programmes, i.e. code.
