magically just works

If we use Bitcoin as an example, it magically just works by consuming a pretty extravagant amount of electricity for the miners/nodes to run.

There are 95,000 physical bank branches in the US and 500,000 employees at the 3 biggest banks alone.

Of course bitcoin doesn't do everything those banks do yet, but on a per-transaction basis it uses orders of magnitude less resources than the current system

What? Can bitcoin count cash and provide a human face to a person whenever they want?

Of course bitcoin doesn't do everything those banks do

You don't have to replace 100% of what something does to disrupt it

Do you want a human face in person to deal give you permission to use your own money (from 9 to 5 with an hour for lunch) or do you just want to be able to use your own money electronically without having to hand it over to someone first?

The bank I work at employees 70,000 people and has ginormous computers too. You should see our resource usage.
