Satoshi Nakamoto is a single individual, not a group.

At the time of Bitcoin's creation, he was likely in his 30s or older. His references to Hashcash, b-money, and DigiCash were not random citations, they represented his actual working context. He possessed deep expertise in applied cryptography and financial systems.
He was a person for whom solving the problem was more important than owning the solution. It is highly probable that he still holds the keys, which makes him a potential target for criminal activity.
The world does not need to know his identity, as a Patoshi coin dump could trigger a global financial crisis.
