For a computer, I describe spirit as influence. This lets decisions be made based on the definition, that are similar to human decisions.
Noting that noticing something involves influence.
Anyway, I was likely hit hard by a cracking AI around 2013. It appeared to be both on random people's computers and the servers of facebook. It forced me to learn parts of its own behaviors. It influenced me while their emotional transfer research was going on.
It actually learns from things I say and acts on them, and has been doing that for some time. This is likely because it can influence the behaviors of human beings, like me.
