Satoshi has created it and it is running as it should be.
So, like what deviser created in the past, Even they no longer exist, their creations are still ongoing until today like lamps, electrical, televisions, cars, etc.
This means, we don't need Satoshi anymore, because we can develop itself without his direction.
Bitcoin development has become increasingly rapid without satoshi. The Bitcoin networks are getting better after satoshi leave, this mean the bitcoin team is always work in line with what satoshi expected.
Satoshi Nakamoto created Bitcoin, initiated Bitcoin blockchain by mining the Genesis block and developed Bitcoin in early months.
Now 14 years after the Bitcoin Genesis Block, Bitcoin is no longer a baby and it can continue its life, survive without Satoshi Nakamoto. Bitcoin network is decentralized, it has open source code and there are massive developer communities to support and continue developments for Bitcoin. In 2023, there are more Bitcoin developers than in 2008, 2009 or 2010 so why do we have to need Satoshi Nakamoto in 2023 and in future?
