Is the US Dollar still as good as gold throught out the world ?

Or have we sank and have been replaced by another top currency ?

I recall years ago;friends of my family that were world travelers told me of how in many countries through out the world {specially 3rd world countries}
The US dollars was revered above their own country’s currency !
e.g Russian,Czech Republic,Thailand,,,etc etc.. street vendors,cab drivers and the like,would rather get paid with US dollars and would have huge smiles as if they were being paid with gold or precious jewels.
*This question is not about the US Gold standard !
