You mean like a virus?

Self replication and self preservation are the essence of life and evolution. There is no primary purpose to a biological system other than self preservation and replication.

Dont forget that a computer program exists in the physical world. It is not unlikely for AI that understands self, to also want to preserve self.

I think we are getting closer to furthering the concept that dreaming isn't just a side-effect of thinking (or simply a defrag/clean-up routine upon the previous day's thoughts or the mind's expectations for tomorrow). It is itself the key to the thinking process, and sits above and commands the other "agents". It helps us deal with uncertainty and lack of rationality inherent in the universe and our incomplete under…

Perception operates like guided hallucination.

> As far as I have experienced its just noise on the wire that we sometimes are conscious enough to recognize. If it was actual noise it would have absolute minimal statistical chance of having any coherent structure.

It's noise in brainspace, which is already structured.

I don't think that explanation has much content.

Mangled data with structure are not noise -- at worse they contain some noise (like a dirty dataset).

I don't understand this obsession with the "purpose" of dreaming. As far as I have experienced its just noise on the wire that we sometimes are conscious enough to recognize. Having spent enough time in extremely sleep-deprived states for projects recently, I've experienced firsthand a lot of funky stuff going on (e.g. falling asleep and waking up with a full page of class notes in front of me, or realizing that I've…

I have never experienced this. How sleep-deprived do you have to be before you start dreaming while editing a document?

Consider a c struct describing a circle, with fields for position, radius, and color. Imagine you have a buffer full of random noise, and you cast it to an array of said structure. You then render the array to a screen, you'll get a bunch of randomly placed colorful circles, rather than a bunch of visual noise.

You know how every generation conceives of the brain as a machine that's analogous to the latest technology of that generation? Like in the 19th century, the brain was a steam engine, and then in the 20th it was a computer? Well, apparently now the brain is a smartphone.

with all the blood pumping ther is certainly a hydraulic aspect

Taking some time to reflect on and consider my own thinking behavior has been interesting. Just like exploring any other system, subjecting myself to sleep stress (in order to meet aggressive deadlines) has allowed me to see what happens when certain things fail, revealing functional boundaries. I see it as kind of analogous to when you starve a circuit/device of power - it behaves in unexpected ways, revealing imple…

That's the "sound" of your braincells dying. At least that's what I heard relating to tinitus.

We won't have true AI until AI stands on its own. Just as a bootstrapped compiler can compile itself, an AI should be capable to reinvent itself without outside help. Until then, it's just a child-AI, dependent on human brains to be designed and optimized.

But humans aren't even capable of that, and we are intelligent. It still takes a lifetime of learning and experience to create a functional human being, and many never get it right.

Yes, but until AI is better than humans at everything it will not be perceived as intelligent, because true intelligence will be redefined as one of the things AI still is not capable.
