A Problem In Comparing Consciousness And Computers Is That we often misunderstand the fundamental nature of both. COMPARE.EDU.VN offers a comprehensive exploration, delving into the misconceptions and complexities of this comparison. By clarifying key concepts and addressing common assumptions, we aim to provide a clear and insightful understanding, leading to better decision-making. Explore topics like artificial intelligence and cognitive computing further.
1. What Makes Comparing Consciousness and Computers So Challenging?
A problem in comparing consciousness and computers is that it stems from differing understandings of what each truly represents. Many hidden assumptions and misconceptions cloud our ability to draw meaningful parallels. We tend to oversimplify the brain’s intricate processes while overestimating the capabilities of current computational models.
1.1. The Elusive Nature of Consciousness
Defining consciousness remains a significant hurdle. Is it simply awareness, self-awareness, subjective experience, or a combination of all these? The lack of a universally accepted definition makes it difficult to establish a baseline for comparison with computers, which operate on clearly defined principles.
1.2. The Reductionist View of the Brain
Many attempts to compare computers and consciousness are based on a reductionist view of the brain. The brain is seen as an information processor, similar to a computer, with neurons acting as transistors. This ignores the brain’s complex chemical, electrical, and biological processes, which are likely crucial to consciousness.
1.3. The Limits of Current Computational Models
Current computer architectures are fundamentally different from the brain. Computers excel at performing logical operations based on predetermined algorithms, while the brain is more adaptable, learning through experience and exhibiting non-linear dynamics. Can our existing models truly capture the essence of consciousness?
1.4. The Mind-Body Problem
The age-old philosophical problem of how consciousness (the mind) arises from physical matter (the brain) further complicates the comparison. If we cannot fully explain how consciousness originates in biological systems, how can we hope to replicate it in artificial ones?
2. What Are The Key Assumptions and Misconceptions To Address?
Several assumptions and misconceptions underpin the difficulty in comparing consciousness and computers. Addressing these is crucial for a more nuanced understanding.
2.1. The Brain As a Simple Computer
One major misconception is that the brain operates like a standard digital computer, processing information in a linear, algorithmic way. Research suggests that the brain engages in complex, parallel processing, utilizing techniques such as neuromodulation (Nusbaum et al., 2001) and sparse coding (Tetzlaff et al., 2012), which are not replicated in conventional computers. The brain also uses Sub-threshold oscillations; neurons are never in a static state and their membranes present fluctuations that could still be informative.
2.2. Computation Is The Same As Information Processing
The assumption that computation is equivalent to information processing is also problematic. Computation implies syntactic and symbolic manipulation of information (Searle, 1990), whereas the brain appears to be capable of interpreting and assigning meaning to information, a function beyond mere computation.
2.3. Hardware Independence
The notion that information processing is independent of the underlying hardware is another misconception. The brain’s physical properties, such as its complex network of neurons and the role of glial cells (Alvarez-maubecin et al., 2000), are likely integral to its function. Ignoring these physical aspects in computer models may lead to inaccurate comparisons.
2.4. Consciousness Arises From Computational Power
Many believe that consciousness will emerge spontaneously as computers become more powerful. Research suggests that the structure and organization of a system are more important than computational capacity (Tononi and Koch, 2015). The cerebellum, for example, has more neurons than the rest of the brain but doesn’t play a significant role in consciousness.
2.5. Reverse Engineering Is Sufficient
The idea that we can simply reverse engineer the brain to understand and replicate consciousness is also flawed. Even with advanced neuroscience techniques, we struggle to understand the workings of simple computing devices like microprocessors (Jonas and Kording, 2017). Reverse engineering alone is insufficient.
3. What Role Do Emotions and Subjective Experiences Play in Consciousness?
A crucial aspect that often gets overlooked in comparing consciousness and computers is the role of emotions and subjective experiences.
3.1. The Limits of Rational Intelligence
Much of AI development focuses on rational, algorithmic intelligence. Human intelligence, however, is deeply intertwined with emotions. These emotions influence learning, memory, and decision-making, leading to non-optimal but often advantageous outcomes. Implementing emotions logically in machines is challenging because actual human emotions interfere with optimal decisions.
3.2. Subjective Experience As a Key Ingredient
Subjective experience, the personal and unique way we perceive the world, is a defining feature of consciousness. Replicating this subjectivity in machines is a major challenge. It requires creating systems that can not only process information but also have a sense of self and a personal perspective.
3.3. The Importance of Embodiment
Embodiment, the physical presence of a body, also plays a role in consciousness. Our bodies provide us with sensory input and allow us to interact with the world, shaping our experiences and sense of self. Simulating this embodied experience in machines is a complex task.
4. How Can We Better Define Human Intelligence?
To accurately compare computers and consciousness, we must first define what we mean by human intelligence. A narrow focus on logical reasoning is insufficient.
4.1. Autonomy and Reproduction
One potential definition of a living being includes two key characteristics: autonomy (self-governance) and reproduction. A system or network of processes that maintains and regenerates itself interacts with its environment to sustain autonomy and increase its reproductive capabilities.
4.2. Morality As a Distinctive Feature
Morality, the ability to distinguish between right and wrong, is another potential defining feature of human intelligence. This involves integrating rational and emotional thinking to make context-dependent decisions. While animals may exhibit some form of morality, human morality is characterized by its complexity and adaptability.
4.3. A Comprehensive Definition of Intelligence
A comprehensive definition of intelligence is the ability of a system to leverage its environment to achieve a goal. For living beings, this goal is survival through autonomy and reproduction. For machines, it is solving a specific task. Human intelligence, therefore, is the ability to use the social environment to sustain autonomy and reproduction through a balance of rational and emotional information processing.
5. What Is The Moral Test?
From the definition of human intelligence stated above, it seems better to suggest a test founded on moral dilemmas more than simple day to day questions (Signorelli and Arsiwalla, 2018). Moral dilemmas are simple, in the sense that they do not require any kind of specific knowledge, but at the same time very complex even for humans, because some of them require a deep understanding of each situation, and deep reflexion to balance moral consequences, emotions, and optimal solutions. No answer is completely correct, they are context dependent, and solutions can vary among cultures, subjects, or even across the same subject in particular emotional circumstances. In other words, a moral test, grounded on moral thinking, needs intermediate processes which are characteristics of high-level cognition in human, as for example self-reflection, sense of confidence and empathy, among others. Hence, a machine will reach part of what it is defined as human intelligence if the machine is able to show autonomously speaking the intricate type of thinking that humans have when they are confronted to these kinds of dilemmas.
5.1. The Need for Moral Thinking
Many experts suggest a test based on moral dilemmas to evaluate machine intelligence (Signorelli and Arsiwalla, 2018). These dilemmas don’t require specific knowledge but demand deep understanding, emotional balance, and moral reasoning. The responses reveal whether a machine can demonstrate the intricate thinking processes characteristic of human cognition.
5.2. The Boat Dilemma
Consider this scenario: A lifeboat has only one space left after a shipwreck. Do you admit a healthy young dog or an injured old man? The answer isn’t simple, and is debated in biomedical research and animal experimentation.
5.3. What Characteristics Are Needed for Moral Thought?
What factors might go into reaching a moral decision? The key is not the conclusion, but the reasoning process itself. Moral thinking needs a nuanced approach that incorporates self-reflection, mental imagery, context awareness, and empathy, processes closely linked to consciousness. Therefore, a moral test functions as a consciousness test.
6. What Types of Cognition Should Be Considered?
Defining different types of cognition, based on awareness and self-reference, can help classify machines and their potential for human-like intelligence.
6.1. Type 0 Cognition
Systems with Type 0 Cognition lack both awareness and self-reference. In humans, this is seen in automatic motor control, like moving muscles without conscious thought. It’s also associated with extraction of individual word meaning and primary attention sometimes called priming.
6.2. Type 1 Cognition
Type 1 Cognition emerges when a system is aware of its internal and external content but doesn’t monitor its manipulations. This includes holistic information, mental imagery, emotions, and voluntary attention. For example, consider how subjects react to fallacy questions where they react with intuitive answers that are typically wrong.
6.3. Type 2 Cognition
Type 2 Cognition involves both awareness and self-reference, allowing manipulation of content. This includes self-reflection, rational thinking, error detection, and complex meaning-making. These processes are essential for human morality.
6.4. Type ∞ Cognition
Type ∞ Cognition is a speculative category where a system manipulates content without awareness. This could resemble an automaton, with self-reference but no ability to extract meaning. There is currently not a biological example of this category.
7. How Do These Cognition Types Relate To Machine Intelligence?
Classifying machines by their cognitive level can help us understand the requirements for achieving human-like intelligence.
7.1. Machine-Machine Type 0 Cognition
These machines lack awareness and cannot know what they know. Examples are robots with a high learning curve. According to the general definition in section A Sub Set of Human Capabilities, machine machines are not intelligent.
7.2. Conscious-Machine Type 1 Cognition
Conscious Machines possess awareness and exhibit Type 1 Cognition, they’re smart, they cannot voluntarily control their inner processes, and they make mistakes. They access broad information but struggle with algorithmic calculations.
7.3. Super Machine Type 2 Cognition
Super Machines are the closest to human intelligence, combining awareness and self-reference. They demonstrate some kind of “thoughts” associated with consciousness as a whole of rational and emotional processes. While their morality may differ from humans, they possess self-reflection, empathy, and context awareness.
7.4. Subjective-Machine Type ∞ Cognition
Subjective Machines deviate from humans, missing awareness but retaining self-reference. They may exhibit supra-reasoning, with unique self-reflection, but lack meaning extraction.
8. What Is The Consciousness Interaction Hypotheses?
One way is to understand consciousness as intrinsic property due to the particular form of information processing in the brain. Here, consciousness will be interpreted in this way, as the dynamic interaction/interference (which can be superposition or interference) of different neural networks dynamics, trying to integrate information to solve each particular network problem. More specifically, the brain could be divided into different “principal layers” (topologically speaking, it corresponds to the architecture component) which are also composed by different levels of layers (hypothesis 1), each principal layer as one kind of neural network interconnected at different levels with other networks (Figure 5). Each principal layer can process information thanks to oscillatory properties and independently of other principal layers (hypothesis 2); however, when they are activated at the same time to solve independent problems, the interaction generates a kind of interference on each intrinsic process (hypothesis 3, the processing component). From this interaction and interference would emerge consciousness as a whole (hypothesis 4). I will call it: Consciousness interaction hypotheses. Consciousness would be defined as a process of processes which mainly interferes with neural integration. These processes are an indivisible part of consciousness, and from their interaction/interference, consciousness emerges as a field of electrical, chemical, and kinaesthetic fluctuations.
8.1. The Principle
The dynamic interaction between different neural network dynamics creates consciousness and allows them to integrate information to solve particular network problems. The brain is divided into principle layers, with each layer able to process information thanks to oscillatory properties independent of other principle layers.
8.2. Two Interpretations
There are two interpretations about these principal layers. 1) Principal layers are formed by areas structurally connected. 2) Principal layers are formed by areas functionally or virtually connected, with the functional connectivity defined by phases and frequency dynamics.
8.3. Superposition and Subtraction
The nature of interference is superposition and the other times take the form of subtraction in the threshold and/or sub-threshold oscillatory activity associated with neural integration, in two or more principal layers. From this interaction and interference, each principle layer monitors the other without any hierarchical predominance between layers.
9. What Implications Does All of This Have On Artificial Intelligence?
There are implications for Artificial Intelligence and Conscious Machines when attempting to accomplish conscious machines and overcome human capabilities. One must start by defining a set or subset of human capabilities to imitate or exceed such as: Autonomy, reproduction and moral.
9.1. Autonomy and Reproduction
Autonomy is one characteristic considered in AI. The goal is to obtain autonomous robots and machines. The same can be expected for machine reproduction, robots that can repair themselves and make their own replications.
9.2. The Critical Review of Human Brain Characteristics
Consciousness is identified as an emergent property that requires at least two other emergent processes: awareness and self-reference. With these processes, its expected to develop high-level cognition which involves self-reflection, mental imagery, subjectivity, sense of confidence, etc, needed to show moral thinking. The way to reach and overcome human features is trying to implement consciousness in robots to attain moral thinking.
9.3. What Does This Accomplish?
By implementing consciousness in robots, a theory is needed that can explain consciousness in human brains, dynamics of possible correlates of consciousness, the psychological phenomenon associated with conscious behavior, and mechanisms that can be replicated into machines.
10. What Paradoxes Emerge From This Idea?
Several paradoxes emerge when trying to reach conscious machines and overcome human capabilities.
10.1. Losing Characteristics
The only way to reach conscious machines and potentially overcome human capabilities with computers is by making machines which are not computers anymore. Any conscious machine is not a useful machine anymore, unless they want to collaborate with us. The machine can do whatever it wants.
10.2. Interference In Processing
When making conscious machines type 1 and/or type 2 cognition, a process of interference, due to consciousness, will affect the global processing of information, allowing extraordinary rational or emotional abilities, but never both extraordinary capabilities at the same time or even in the same individual.
10.3. What is Considered Intelligent?
If humans are able to build a conscious machine that overcomes human capabilities: Is the machine more intelligent than humans or are humans still more intelligent because we could build it?
