Opinion: It’s arrogant to assume humans will never imbue AI with consciousness – The Next Web

Cogito, ergo sum, Rene Descartes. Translation: I think, therefore I am.

What makes us, us? How is it that were able to look at a tree and see beauty, hear a song and feel moved, or take comfort in the smell of rain or the taste of coffee? How do we know we still exist when we close our eyes and lie in silence? To date, science doesnt have an answer to those questions.

In fact, it doesnt even have a unified theory. And thats because we cant simulate consciousness. All we can do is try to reverse-engineer it by studying living beings. Artificial intelligence, coupled with quantum computing, could solve this problem and provide the breakthrough insight scientists need to unravel the mysteries of consciousness. But first we need to take the solution seriously.

Theres been a rash of recent articleswritten by experts claiming definitively that a machine will never have consciousness. This represents a healthy level of skepticism, which is necessary for science to thrive, but there isnt a lot of room for absolutes when theoretical future-tech is involved.

An untold number of experts have weighed in on the idea of sentient machines computers with the capacity to feel alive and, for the most part, they all believe the idea of a living robot is science fiction, at least for now. And it is. But so too are the ideas of warp drives, teleportation, and time travel.

Yet, as you can see, each of these far-out ideas are not only plausible, but grounded in serious research:

We could be hundreds or thousands of years away from conscious AI, but thats a drop in theocean of time compared to never.

The prehistoric scientists working on the problem of replicating naturally occurring fire and harnessing it as an energy source may have been the brightest minds of their time, but their collective knowledge on thermodynamics would pale beside an average 5th graders today. Recent work in the fields of quantum computing and artificial intelligence may not show a direct path to machine consciousness, but theories that say it cannot happen are trying to prove a negative.

We cannot definitively say that intelligent extraterrestrial life does not exist simply because theres evidence that life on Earth is a universal anomaly.And, equally so, we cannot logically say machines will never have consciousness simply because we havent figured out how to imbue them with it yet. Citing the difficulty of a problem isnt evidence that its unsolvable.

Somehow, consciousness as we understand it manifested in the universe once. It seems arrogant to imagine we understand its limits and boundaries or that it cannot emerge as part of a quantum function in a machine system by the direction or invention of a human.

But, before we can even consider the problem of building machines that feel, we need to figure out what consciousnessactuallyis.

Scientists tend to agree that consciousness is the feeling of being alive. While we cant be sure, we like to think that animals are living and conscious, and plants are just living. We generally assume non-living things are not conscious or aware of their existence.But we dont know.

The reason we dont know that grass and clouds arent conscious is that we cant measure consciousness. As researcher Philip Goff points out in this article, we can only measure the activity associated with consciousness, not the awareness itself. Goff writes:

The best scientists are able to do is to correlate unobservable experiences with observable processes, by scanning peoples brains and relying on their reports regarding their private conscious experiences. But how do you detect and measure the feeling of being alive?

We know that consciousness cant depend on the kind of feeling that comes from our senses. We can easily demonstrate that none of the five senses are necessary for the mind to emerge. We do not need our eyesight, hearing, sense of touch, ability to smell, or taste buds, or even our physicalbody to be considered conscious (see: brain in a jar).

Two main schools of thought have risen to prominence over the millennia to explain where consciousness comes from: Panpsychismand dualism. The former says all matter is imbued with consciousness and humans got a lions share, the latter states matter and consciousness are separate entities and consciousness works like the religious idea of a soul.

It boils down to whether you choose to believe that trees, rocks, stars, and subatomic particles all have a modicum of consciousness, or if you prefer thinking that only certain entities have the spark humans, good doggos, and dolphins seem like proper candidates.

Theres also a third option: what we describe as consciousness is merely a derivative function of the unconscious act of observing the universe. In essence, consciousness isnt its own thing anymore than an inch or a hour are tangible constructs. Consciousness is, by this theory, just a generalized measurement: our existence isnt necessary to the universe, but our consciousness is necessary for observation to take place. If there were nothing around to observe the universe, it might not exist. An unconscious entity, by definition, cannot observe.

That may sound like an if a tree falls in the woods and nobodys there to hear it, does it make a noise? kind of statement, but its rooted in quantum theory. At the core of quantum mechanics lies an idea called superposition. The tiniest particles in the universe work together to form systems, and these systems determine how energy and matter conduct themselves. These tiny specks manage this by aligning themselves in quantum states where each particle can be one way, another, or both ways at the same time.

Think about it like thetifo fan displays you often see in live coverage of sporting events. The ones where the members of the crowd hold up individual signs to display a giant image or spell out huge words for the TV audience:

At the perfect moment in every quantum system, subatomic particles in a state of superposition choose to end up in one resulting position, another, or both at the same time. Quantum mechanics tells us that quantum particles act differently when theyre observed.

If you can imagine this on ascalegazillions of orders larger than our brains can compute, thats how the quantum universe functions. Probably. Its all theoretical at this point, though quantum mechanics is more like the theory of gravity or evolution in that its a very, very strong theory.

By attempting to replicate brain function in machines, AI researchers and neuroscientists are hunting down the trail of consciousness. Our only lead right now is the organic brain. If we can figure out how real brains work, we may be able to accurately simulate cognitive function, chaos, and organic memory.

Under current research paradigms, simulating a brain is about as close to impossible as a task can get. We dont know enough about how the brain works and, chances are, classical computers will never emulate the mind because they just run algorithms and make calculations. Binary computers, to date, cant approximate thought.

Quantum systems, however, have the potential to simulate naturally occurring processes that classical ones cannot. For example, theoretically,both the human brain and a quantum computer can time-travel to solve problems, classical computers cannot.

Its not beyond the realm of possibility that huge swaths of missing information on the nature of consciousness will be gleaned in the quest to simulate and, ultimately, synthesize organic brains.

This, of course, doesnt indicate that machines will ever have consciousness, but itd be arrogant to assume that technology has nothing to teach us about ourselves. Especially when you consider how little we currently know.
