"Magic Computer Money" as a specific phrase was a joke.
The idea that Bitcoin should be demonstrated and used as opposed to explained is something I stand firmly behind. Do you explain the federal reserve and fractional reserve banking to everyone before you hand them a dollar? No. People don't really want to understand money, they just want to use it. Likewise, Bitcoin is superior money because using it is easier. Therefore, if they simply use it, they do not need to and never will understand it.
