I certainly hope not! A cashless society is the wet dream of those who would turn the world into a panopticon!
It'd add every teensiest financial transaction you ever make to the list of information about you that every major government/company/crime syndicate will have easy access to. No thanks!
(Note that stuff like bitcoin is a form of cash money.)
Ok, yeah, I meant post-tangible currency, but that's just a mouthful.
I was using the English vernacular version of "cash" to refer to stuff you can touch, not the specialized bookkeeping meaning (which could even include diamonds or some artwork in certain situations).
I will admit though that the price I set for "knowing everything about my transactions" is roughly around 1% cash back, so as a volunteer to the panopticon, I can't raise too much outrage either way.
I hear you, but certainly can't interpret the linked article in that way. It explicitly mentions the ability to track all transactions as an (if not the) desired effect.
About extended meanings of the term "cash", any serious prepper will have some amount of cheap spirits and maybe cigarettes stockpiled. In the end, these are a kind of consumable emergency cash.
