Truth or conspiracy theory? USD may be obselete in near future

I mean you never know. That is all I can say.. You never know what may lie in the future, or whether everything is just the signs of a paranoid group of people who are looking out for the worst when times are rough. I saw another video about US currency changing into the Amero... In the meantime I may possibly open up a Swiss or British bank account just in case. lol.
