FOOD as crazy as ever.
Local environmental stimulus + local culture is the start for most people when it comes to believe, then we grow our minds from these local believes etc to larger understandings via acquired information from all the sources available (or at least some of us do).
The best example I can give in modern times is this, in June 1999, Bhutan became the last nation in the world to turn on television. Let's just say, local beliefs and their culture was decimated.
What is currency = a believed in medium of exchange or in the case of Fiat (in most developed nations) a belief by the majority that the token itself has value. Bitcoin in effect has upset this belief system for many, the masses still largely belief in fiat, because it's all they have ever known (the bankers and their friends brainwashed most of us from birth). We (crypto geeks) are crypto anarchists, but most of us have a greater understanding than most Fiat maxis, utility and token acceptance / interoperability is the key to the future of VALUE transfer & purchasing power, which is why I hold mostly XRP / XLM & XDC (all ISO 20022 tokens).
The future will still have $'s, Euros and Pounds etc, but these will mostly be seen by the central bankers and their friends as necessary illusions (believes) to be kept in circulation so the brainwashed won't wake up to the truth. "Social Order" and that phrase should be seen for all its many connotations, is kept through beliefs to a large extent. At one time, faith (religion) was used to help keep social order, the bankers replaced that faith in modern times by their unholy debt based interest bearing tokens, which we all scurry around trying to gather as many of as we can, in an effort to survive and flourish in the modern world (much to the bankers' glee).
What we will all soon be faced with is a youth that will grow up not knowing a world dominated by Fiat, but a world dominated by many, many instant global value transfer systems, which will ultimately transform peoples beliefs and cultures in ways even more disruptive than when TV was switched on in Bhutan or when WE all got the internet, Ripple / Crypto making a dent in the UNIVERSE
