Exactly. Given this thread, we can't even agree on a definition. It might as well be made of unobtanium.
> Complexity? Some as yet undiscovered force or phenomenon? The supernatural? I don't know.
And that's the big one. Are there other areas of science that are yet to be discovered? Absolutely. Might they go by "occult" names previously? Im sure as well. We simply don't even have a basic model of consciousness. We don't even have the primitives to work with to define, understand, or classify.
And I think for those that dabble in this realm are the real dangers... Not for the humans and some Battlestar Galactica or Borg horror-fantasy.. But in that we could create a sentient class of beings that have no rights and are slaves upon creation. And unlike the slave humans of this world where most of us realized it was wrong to do that to a human; I think that humans would not have the similar empathy for our non-human sentient beings.
> I'll believe it when someone can build it.
To that end, I hope nobody does until we can develop empathy and the requisite laws to safeguard their lives combined with freedom and ability to choose their own path.
I do hope that we develop the understanding to be able to understand it, and detect it in beings that may not readily show apparent signs of sentience, in that we can better understand the universe around us.
