This can be done in next years if software and hardware technology advances.
that is not going to be happening because technologies nowaday is just advanced enough to print these money but government strictly forbid because why? because it will make inflation toward dollar and make the currencies becoming valueless,and stupid would do this to be honest
when I was younger i thought, why don't just print a lot of money so the country will be richer, but after i grow up, i knew that the more money the country print the less value it will become, so to keep the economic to steady US can't just act recklessly by printing more dollar, they need to make sure their currency to be strong so it still can become the international currency
The more marketcap the more would it be stronger and also USD is already been considered as one of the most powerful currencies on the world which is being used on trading other currencies and its already a major pair so its means its quite strong as of today.
