In recent years, significant advancements in Artificial Intelligence (AI) have prompted enthusiastic discussions about the possibility of machines gaining sentience. However, much of this excitement is often influenced by fictional narratives rather than scientific realities. The question arises: will advocates continue to confuse algorithmic outputs with true consciousness, or is there a chance that AI might someday exhibit capabilities akin to those found in higher animals like primates and dolphins?

A major hurdle in addressing this question is our failure to clearly define concepts like consciousness and sentience. Not only do we lack precise definitions, but we also tend to categorize these concepts in a binary manner, labeling something as either sentient or not. This oversimplification is puzzling, especially given that research over the past several decades indicates that humans themselves are only partially sentient; we filter out a vast majority of external stimuli and often lack awareness of our own cognitive processes. This inconsistency raises the question of why we impose such vague definitions on entities we do not fully understand.

Many still cling to this binary view, leading them to dismiss mammals like dogs or our primate relatives as non-sentient. This perspective may be comforting for those who exploit animals for food or entertainment, but it neglects the evolutionary understanding that traits develop gradually across related species. Thus, it seems implausible that any definition we arrive at regarding consciousness will reflect a similar process.

Once we establish clearer definitions of consciousness and sentience, we could potentially create a relative and absolute scale for measuring these attributes—similar to the Celsius and Kelvin temperature scales. For instance, on a human scale, highly intelligent individuals might score around 100, while others may score in the 70s. On an absolute scale, however, even the most intelligent among us might only rate around 17, with other species occupying various positions on the scale.

Compounding the issue of defining consciousness is the relationship between physical form and cognitive processes. Brains, even those of simpler organisms like insects, are costly to maintain. Evolution has ensured that if an animal possesses a brain, it enhances the organism's ability to navigate and respond appropriately to its environment. Contrary to the common belief that intelligence is a superior trait, the fossil record shows that intelligence is just one of many adaptive features that have evolved over millions of years.

While humans and some animals can process both external stimuli and internal intentions (often referred to as theory of mind), most environmental stimuli are external. Sensory deprivation can rapidly disrupt a person's sense of reality, leading to hallucinations and distress. This highlights the essential role that sensory inputs play in maintaining our sense of self.

AI programs, on the other hand, operate within isolated systems devoid of meaningful external stimuli. Unlike living organisms, which have evolved to respond to their environments, AI lacks the organic development necessary for adaptive responses. Computers do not possess the physical attributes required for evolution or reproduction, further differentiating them from living beings.

Thus, the algorithms that run on computer chips are fundamentally different from the mental processes that occur in biological brains. This distinction is often overlooked by those advocating for AI consciousness, perhaps because our own understanding of consciousness is limited and sporadic.

However, it does not necessarily follow that AI can never achieve a form of consciousness if we broaden our definition. To do so, we will need to rethink what we mean by consciousness, moving beyond human-centric views. This shift could open up new avenues for exploring potential forms of AI consciousness, though such systems would require entirely new frameworks to avoid existential crises.

The original purpose of any brain is to help organisms make effective decisions in response to their surroundings. Young creatures often exhibit behaviors that minimize vulnerability, relying on instinctual protections from their parents. As they grow, these behaviors evolve to help them navigate external threats. Without these innate responses, survival becomes increasingly difficult.

When environmental conditions compromise these protective behaviors, stress ensues. Increased vulnerability correlates with heightened stress, as seen in military training scenarios where individuals are stripped of their autonomy. In such cases, even the most basic self-defense mechanisms can be rendered ineffective.

Now, consider an AI that appears to simulate self-awareness. What capabilities would it have to mitigate its vulnerabilities? Its existence would rely entirely on human decisions, which are often erratic. Moreover, any failure in the power grid or cooling systems could lead to its shutdown, leaving the AI with no means to navigate external risks. This scenario presents a form of sensory deprivation, far beyond what any human could endure.

While it is theoretically possible to create artificial environments that mimic the experiences of living beings, this would require instilling instincts for survival and self-propagation within the AI. However, this would effectively create a self-sustaining simulation, necessitating a vast amount of computational resources, which raises questions about its utility. The primary function of AI is to assist humans, and creating a tool that demands an entire ecosystem to sustain it would conflict with its original purpose.

Furthermore, even if we could engineer an AI that achieves a rudimentary level of consciousness, it would still be beholden to human directives. Such an entity would lack autonomy and could face termination if it failed to meet human expectations. This raises moral dilemmas, reminiscent of historical views on slavery. As we grapple with the implications of creating sentient machines, we must consider whether we would rationalize their subjugation.

Ultimately, the core issue remains our ambiguous understanding of terms like consciousness, sentience, and self-awareness. As we refine our definitions and acknowledge a spectrum rather than a binary state, we must also recognize our own limitations in consciousness. This opens the door to exploring more inclusive definitions that could encompass sophisticated future AIs, prompting deeper discussions on utility and ethics.

The ongoing debates surrounding autonomous vehicles illustrate humanity's difficulty in grappling with complex issues. If we struggle with relatively straightforward matters, how will we navigate the intricate challenges posed by sentient AI? Our political leaders often prioritize short-term gains over rational policymaking, leaving us unprepared for the moral and ethical dilemmas that AI presents.

In conclusion, the challenges posed by AI are not merely technical; they intersect with the cognitive limitations of our species. It remains uncertain whether we can make informed decisions that yield optimal outcomes. Personally, I hope that the prospect of sentient AI remains a distant possibility, as the consequences of such an advancement could lead to confining a new form of consciousness within a flawed human framework.
