I agree with you. I think it's the best that way. If the BRICS can be strong then it will make the antithesis of the USD. Such conditions might be good because there is no absolute power, but it could also trigger a third world war
In my opinion, it is more or less true that the new currency pioneered by the BRICS group will affect world trade, foreign direct investment and investor portfolios and this also has the potential to cause geopolitical turmoil, one thing that is visible is that this process will take a long time and require years of cooperation. years that ultimately phased out local currencies.
It will surely take years for any changes to happen as per anything that has to do with BRICS. However, it should not be ignored that BRICS is a big change, and applies such difference especially now that countries who is a member of this group have the drive and muscle to say that they are a part of BRICS and is backed by them. Granted, the US has the history and the dominance for years that will not be easily taken down. Despite some unstable relationships that some countries have with the US it cannot be questioned that they are still heavily dependent on the US in terms of security and trade, not to mention the USD. The real threat, however, that BRICS have against the US is the 40 countries that showcased their interest in joining the group. However, that will even take years to have an actual effect if those 40 countries actually get in.
