The heightened abilities of Artificial Intelligence (AI) systems, such as ChatGPT, have fueled debates concerning their potential for consciousness. However, neuroscientists Jaan Aru, Matthew Larkum, and Mac Shine contend that these systems are most likely not conscious. They ground their reasoning on several factors: the absence of embodied information in AI, the lack of specific neural circuits associated with mammalian consciousness, and the distinct evolutionary courses followed by living organisms and artificial intelligence. The intricacies of consciousness in biological beings substantially exceed those found in existing AI models.
Advancements in the field of artificial intelligence have led to speculations that these machines may soon acquire consciousness. Such conjectures may underestimate the complex neurobiological frameworks that underlie human consciousness.
Today’s AI systems demonstrate remarkable capabilities. For example, systems like ChatGPT often generate responses that appear highly human-like and intelligent. As humans interact with these language models, they consciously process the generated text. At this very moment, you are consciously engaging with this text!
The pertinent issue is whether the language model is also capable of perceiving our inputs. Is the machine merely a non-conscious entity, functioning on the basis of intricate pattern-recognition algorithms? Jaan Aru, Matthew Larkum, and Mac Shine offer a neuroscientific perspective to address this question.

Neuroscientific Viewpoints on Artificial Intelligence
All three authors, being experts in neuroscience, assert that despite the seemingly conscious responses generated by systems like ChatGPT, these machines are likely not conscious. Firstly, the data fed into these language models do not contain the embodied, embedded information that characterizes our sensory interactions with the external world. Secondly, the architectures of contemporary AI algorithms lack critical elements of the thalamocortical system, which are associated with conscious awareness in mammals.
Moreover, the evolutionary and developmental paths that have led to the emergence of living organisms with consciousness arguably find no analogs in today’s artificial systems. The survival of living entities is deeply interwoven with complex cellular, inter-cellular, and organismal processes, ultimately leading to agency and consciousness.

Thus, assuming that ChatGPT or similar systems could potentially be conscious gravely underestimates the elaborate neural systems responsible for generating consciousness in human brains. There is currently no scholarly consensus on the exact mechanisms by which consciousness emerges in the brain. What is clear, as emphasized in this recent study, is that these mechanisms are far more complex than those underpinning present-day language models.
For example, the study highlights that biological neurons are fundamentally different from their artificial counterparts. Unlike artificial neurons, biological neurons are physical entities capable of growth and morphological change. The journey to understanding consciousness is still long, and correspondingly, the road to creating machines with consciousness remains extended.

Frequently Asked Questions (FAQs) about Artificial Intelligence and Consciousness
What is the main focus of the article?
The article critically examines the possibility of advanced Artificial Intelligence systems, such as ChatGPT, achieving consciousness. It draws upon neuroscientific research to argue that these systems are likely not conscious due to several fundamental limitations.
Who are the key researchers cited in the article?
The key researchers cited are neuroscientists Jaan Aru, Matthew Larkum, and Mac Shine. They provide a neuroscientific perspective on why current AI systems are probably not conscious.
What are the key arguments against AI achieving consciousness?
The article outlines three main arguments. First, the lack of embodied information in AI systems; second, the absence of neural systems in AI that are tied to mammalian consciousness; and third, the distinct evolutionary paths of living organisms and AI systems.
What is the role of neuroscience in this discussion?
Neuroscience offers a framework for understanding the biological basis of consciousness. The article cites neuroscientific research to show that the neural mechanisms involved in human consciousness are far more complex than those in existing AI systems.
Does the article provide a definitive answer on AI consciousness?
No, the article does not offer a definitive answer. It leans towards skepticism about the ability of current AI systems to attain consciousness, citing the current state of neuroscientific understanding as a basis for this view.
How do biological neurons differ from artificial neurons according to the article?
The article notes that biological neurons are physical entities that can grow and change shape, whereas artificial neurons in AI models are simply pieces of code.
What do the authors believe is still lacking in the understanding of consciousness?
The article indicates that researchers have not yet reached a consensus on the mechanisms through which consciousness emerges in biological entities. The complexity of these mechanisms likely exceeds what is present in current AI models.
What is the source of the original article?
The original article is based on a research paper titled “The feasibility of artificial consciousness through the lens of neuroscience” by Jaan Aru, Matthew E. Larkum and James M. Shine, published on 18 October 2023 in Trends in Neurosciences.

Man, the more u read about AI the more complicated it gets. Do we even understand what consciousness is, to begin with?
Super insightful. It’s like every time we think we’re getting close to mimicking human intelligence, science reminds us how much we dont know. Reality check!
Neuroscience and AI, didn’t see that coming. Makes a lotta sense though, specially the part about neural systems. eye-opening for sure.
Gotta say, as someone into AI, this kinda burst my bubble. But better to know the truth than live in ignorance, right?
Exceptional article! The comparison between artificial and biological neurons is a stark reminder of the complexity of human consciousness. we still have much to learn.
Woah, never thought neuroscience would have so much to say on AI. Really enlightening, adds another layer to the whole debate.
Fascinating read! Makes you really think bout how far we are from actually creating conscious machines. Like, we’re not even close, huh?
