"Crypto" Is Being Redefined as Cryptocurrencies

I also don't like that "literally" now means "figuratively", or using the plural "their" to mean "him or her".
But we don't get to dictate how language is used.
How language is used dictates what is acceptable.
So get over it, Schneier, language is alive.
In fact I had to look up booty call just now and understand immediately the difference.
Whereas "Switzerland should become crypto capital" can mean different things to different people simultaneously. That's the problem. If I look up crypto in a notional 2018 dictionary and it has two definitions, which do I choose?
The term cryptography has always left out the critical importance of operational security and correct implementation and usage of cryptography. Instead of trying to protect "crypto", which is never going to happen, we can choose to use a different term, maybe even one which encompasses a fuller range of concerns. Data security, InfoSec, communication privacy...
I don't know what the best term would be, but "crypto" is never going to go back to unambiguously referring to cryptography. Terms must always adapt to changes around them. "Silent movie" wasn't a term before "talkies" came around. They just called them "movies".
