@davidpetersonharvey @Gargron Imagine telling someone today that e.g. "ssh took the existing usage patterns of rsh and rlogin, but added a layer of crypto for authentication and privacy".

A person in 2005 would have basically understood what ssh is from that description, but I bet you 100 Satoshi that a person from today would be just as likely to ask if that means the user information is on a distributed ledger.
