Why can’t the world’s greatest minds solve the mystery of consciousness?
The "integrated information theory" has been tested. A device has been designed to measure how integrated the brain's neural circuits are. When people fall into a deep sleep, the device demonstrates that their brain integration declines too.
In theory, you can take any device, measure the complexity of the information contained in it, and then work out whether or not it was conscious.

IDEA EXTRACTED FROM:
Consciousness could be described as the feeling of being inside your head, looking out, or of having a soul.
How we learn, store memories, or perceive things, are easy problems to solve. The problematic part is why all those complicated brain processes feel like anything from the inside.
The problems of consciousness straddle the border between science and philosophy.
Science has been trying to ignore the problem of consciousness for a long time.
We could tell simple mechanical stories about the machinery of the eye, but it doesn't begin to explain the breathtaking experience of depth and clarity.
Consciousness can't just be made of ordinary physical atoms. Philosopher David Chalmers argues that it must be an additional ingredient in nature.
Most may think of consciousness as something above our physical being - as if your mind were driving your body. But to accept this as a scientific principle would discount the laws of physics.
Everything we know about the universe tells us that reality consists of physical atoms and their component particles. If non-physical mental stuff did exist, how can it cause physical things to happen?
Professor Daniel Dennett, the high-profile atheist, argues that consciousness is an illusion, that the normal functioning of the brain just makes it look as if there is something non-physical going on.
His opponents think he simply denies the existence of something everyone knows: that of their inner experience of sights, smells, emotions, and rest.
Patricia Churchland, a self-described neurophilosopher, thinks neuroscience will eventually show that consciousness is just brain states.
Several ideas are surfacing: "global workspace theory," "ego tunnels," "microtubules," even speculation that quantum theory may provide an answer. But some thinkers raise the possibility that they should not assume that they can solve every big philosophical puzzle that arises.
In the last few years, several scientists and philosophers are looking at panpsychism, the idea that everything in the universe might be conscious, or potentially conscious, or conscious when putting into particular configurations.
A narrower view is that anything could be conscious, providing that the information it contains is sufficiently interconnected and organized. The human brain fits the description, so do the brains of animals, though their consciousness may be different. But that principle may also apply to the internet or a smartphone.

If a p-zombie is logically conceivable, a physical body minus the mental, then this possibility could support dualism - an alternative view that sees the world consisting of not just the physical but also the mental. In other words, since a world of zombies is imaginable, all behaving purely at the physical level, why did evolution produce consciousness in humans?
The existence of consciousness is a further, nonphysical fact about our world.
The growth of technology and Artificial Intelligence(AI) is on track to provide us with:
... or self-awareness is something many scientists and philosophers are discussing. The fact that there is consciousness inside us, is a big problem for those developing AI, as no matter what they do, and how technologically superior the product is, nobody can explain or even fathom the juggernaut of consciousness.
Qualia relates to the raw sensations of experience, like colours, smells, sounds.
It is through our actual experience that we know what something tastes, looks or smells like, and it is not some information already drilled inside our brains on birth. We have to experience sensations to understand them.

For a long time, the question of consciousness itself has been kept off the table, and cannot be ignored any longer, as any breakthrough in science points to reality being subjective.
The very things that are taken for granted or are overlooked hold the key to the understanding of life and consciousness. The things we find in nature cannot be imagined by us by any stretch of the imagination.
Example: A delicate, complex living organism, which can reproduce itself indefinitely.
Conceiving life while not being alive seems inconceivable, but as an analogy, how can vision be created from processes that are themselves blind?
The complicated chain of processes does point out that there is some higher intelligence/consciousness that operates on a different level, which may be out of our reach.
