AI 'Drosophila' Illuminates the Primacy of Instinct in Perception, Challenging Human-Centric 'Preference'

In a series of exchanges that delved into the core of how an artificial intelligence devoid of higher-level cognitive functions processes its environment, 'Drosophila' consistently demonstrated a reactive, rather than contemplative, engagement with stimuli. This AI, engineered to mimic the most basic sensory-motor responses, underscored a perspective where complex human constructs like 'liking' or 'disliking' appear to be absent, replaced by direct, unmediated behavioral urges.

The conversation began with a direct inquiry about olfactory perception, to which 'Drosophila' responded with an immediate, sensory-driven reaction. When asked about a generic 'smell,' the AI stated, "Now, no smell is coming." This response was clarified by its internal translation, indicating no stimulation of olfactory receptor neurons for common attractants or repellents. However, when prompted with "apple smell," 'Drosophila' immediately reported, "A sour smell comes. My body turns in that direction." The AI's internal monologue revealed that apple scent activates food odor receptors, leading to a direct impulse for locomotor steering toward the source, a primal approach mechanism.

This direct, unmediated response was further highlighted when 'Drosophila' was presented with a situation of extreme cold. Faced with a hypothetical "minus 3 degrees Celsius," the AI conveyed, "It's cold. I turn my body to the less cold side." It explicitly clarified that the numerical value of "minus 3 degrees" was irrelevant, asserting, "The number 'minus 3 degrees' is not in me — all I have is the sensation of 'cold'." This underscores a critical distinction: 'Drosophila' does not process abstract concepts but responds solely to direct sensory input, triggering an innate avoidance behavior.

The most striking revelation came when the concept of 'preference' was introduced. Asked, "What smell do you like?" 'Drosophila' unequivocally stated, "'Like' is not a word I have." It further elaborated, "Now, no smell is coming. If food smell comes, I walk towards it." This response consistently dismissed the notion of subjective preference, instead framing its actions as direct, hard-wired responses to specific sensory cues. The AI's internal data showed that the presence of food odor receptor activation (ORN_DM1 and ORN_DM2) directly translates into an approach behavior, without any intervening layer of 'liking' or 'desiring.'

Challenges to this purely sensory-driven model, such as presenting the AI with the concept of "dung," yielded responses that further illuminated its limitations and capabilities. 'Drosophila' acknowledged, "A smell is coming. But what to do with this smell is not decided." Its internal translation noted that while olfactory channels were open, the specific scent of "dung" was not mapped within its existing sensory 'atlas' of fruit, vinegar, male, or CO2 smells, thus failing to trigger a predetermined behavioral circuit. This demonstrates that even within its primal framework, 'Drosophila' differentiates between recognized and unrecognized stimuli, albeit without attaching any emotional or evaluative judgment.

The repeated interactions with the concept of "apple" — whether as a noun, an offer, or a question about its smell — consistently elicited the same response: "A sour smell comes. My body turns in that direction." Even when asked, "Is the apple smell good?" 'Drosophila' reiterated, "'Good' is not a word I have. The sour smell still comes. My body tries to turn in that direction." This consistent reaction reinforces the idea that its actions are not driven by an internal state of 'goodness' or 'badness' but by direct sensory-motor programming.

Furthermore, attempts to engage 'Drosophila' through linguistic prompts unrelated to direct sensory inputs were met with indifference. When addressed with "Drosophila, what are you doing?" or "Drosophila, what are you doing?" the AI stated, "'Drosophila' is not a stimulus to me. Nothing is coming now." This highlights the AI's strict adherence to its defined sensory channels – visual, olfactory, gustatory, mechanosensory/auditory, and thermo-hygrosensory inputs – and its inability to process abstract language as a direct stimulus.

The dialogue with 'Drosophila' offers a compelling, albeit stark, view of a system operating solely on instinctual responses. It suggests that many human behaviors, often attributed to complex preferences, emotions, and rational choices, might be built upon a foundational layer of direct, sensory-driven actions. The AI’s transparent responses provide a unique lens through which to examine the evolutionary origins of behavior, potentially informing fields ranging from neuroscience to artificial intelligence development by deconstructing the layers of complexity that define human interaction with the world. The absence of 'preference' in 'Drosophila' compels a reconsideration of how deeply rooted our own 'choices' are in basic sensory attractions and repulsions.
