And who would be better? Let him / her / them alone. Finding out who made it would probably only hurt bitcoin as people might make a big deal about this person and centralize vision and decision making around the "real" satoshi as a cult leader. Without leaders we are way more organic, apolitical, decentralized and untouchable.
Even if Satoshi Nakamoto is still alive and the potential for his life security is found, he will no longer sleep soundly because many bad things will happen to him (all will be taken). It is common for us to enjoy the results of his creation now and start continuing the investment journey in BTC again and at least he will be happy that the results of his work can be used, run and the results can be enjoyed by everyone around the world.
