I feel like she’s more of a pragmatist while Sanders is firm and staunch in his ideology. AOC will bend the knee to the Party when she realises she needs to in order to get what she wants, but only just enough so that they don’t hate her guts. Sanders had the luxury of being able to raise the middle finger to the Party because they knew they had to suffer him anyway owing to his huge popularity among the left. Sander’s popularity allows him to remain ideologically pure. AOC doesn’t have the power.
I don’t think a BRICS currency will be successful in replacing the dollar unless the governments of the participating countries force their businesses to use it. The reason why transactions are denominated and settled in US dollars is because of the perceived stability of its value and the openness of the US financial system to international trade. People use the US dollar because they trust the American government to not excessively devalue it and for it to be reliably useful later on.
And yes, I recognise that all of these are under attack by the current US government.
