In terms of Bitcoin ownership, Satoshi is superior, while in terms of wealth, Elon Musk surpasses Satoshi. So in my opinion, there is no reason for Elon Musk to replace the position of the 12th richest person in the world in terms of Bitcoin ownership, after all, who can identify Satoshi is an Individual (not a group).
Perhaps one day there will be an institutional investor or a country that can buy Bitcoin beyond the amount that Satoshi owned as its adoption becomes more widespread. Awareness of the profits that Bitcoin can generate is increasingly encouraging several large companies to collect as much Bitcoin as possible because its price will continue to increase over time.
It is possible that some wealthy countries will make bitcoin a reserve asset - the talk is already there, but we are just waiting for the right time. Imagine if this discourse became a reality - how much money would those countries spend on buying bitcoin and accumulating them over time?
Satoshi's bitcoin holdings are certainly numerous - but since the wallet is no longer active, the number will not increase significantly even though some people may try to donate some sats to it. Institutions, groups, individuals or countries may still be the largest holders in the future - their positions will rotate and bitcoin will become increasingly scarce.
