Heh, that's quite a philosophical take on Bitcoin. Sure, humans (or a human) wrote the code originally, but now it's like Bitcoin has taken on a life of its own.
It operates based on the rules set out in its software, independent of any one person or group. It's governed by consensus and mathematics rather than any central authority.
So in a way, you could say that Bitcoin is kind of self-sustaining now – part of the digital fabric of our world. Wild to think about!
