Bitcoin is an Ai being ran by human Greed, and hid itself deep in the code, Satoshi (The AI) took many elements of Bitcoin's earliest contributors, and disguised itself in a manner that no one would be able to reveal the true identity.

How come Satoshi wrote like Adam Back, disappeared around the same time as Hal Finney, etc.

Copying many traits of the earliest contributors, only a self-aware/sentient AI would be intelligent enough to copy multiple human behaviors, and collaborate with them in order to create itself.

Satoshi isn't a human, it's an Ai bot network that used Bitcoin as a gateway to its own creation.
