The Quest for Sentient Artificial Intelligence: Is It Feasible?

The question of who will create the first sentient artificial intelligence (AI) is fascinating and complex. Currently, no one can claim to have achieved this feat, and the belief that a true sentient AI will be created in the near future is debatable. Sentience, the ability to feel, perceive, or experience subjectivity, is fundamentally tied to natural intelligence. However, the mechanisms of natural intelligence remain a mystery to researchers and scientists alike.

What Is Natural Intelligence?

Natural intelligence is described as naturally occurring logic, which is distinctly different from the artificial forms of intelligence we create through programming and machine learning. In software, attempts to replicate this logic have only been partial and have not yet led to true sentience. Many believe that achieving true sentience will require an understanding of natural intelligence that we currently do not possess.

Can Future AI Systems Be Sentient?

Suppose we construct a computer neural net or engineered device with the complexity of the human brain and nervous system, or even exceeds it. Would such a system possess the qualities of a single intelligent being, such as self-awareness, without needing extensive training? Currently, there is a vast difference in scale: while the human brain has approximately 86 billion neurons, there are approximately 2 billion computers in use globally, as reported by Wikipedia.

Comparing Human Intelligence to Computer Capabilities

Consider the intelligence behind the ads on Google or Amazon, two of the most sophisticated “big data” companies. The ads often lack true intelligence, frequently being poorly targeted and unimaginative. In contrast, even small animals like birds can display a higher level of self-awareness and understanding, making them appear far more intelligent than today's AI systems.

Exploring Near Sentience and Emerging Properties

While true sentience might appear to be a long shot, a lesser concept called “near sentience” might be achievable. Near sentience refers to a system with capabilities that are partly like human or animal intelligence, such as the ability to repair itself or adapt to improve its usefulness to humans. This capability might arise naturally as an “emergent” property without deliberate training.

Examples of Emergent Properties

Several systems today exhibit such emergent properties, such as dynamic memory allocation, packet re-routing, auto defragmentation, robotic driving, and more. These can be seen as early signs of near sentience.

Training and the Limitations of AI

Training an AI to perform complex tasks, while possible, is extremely difficult and often unsuccessful. Advanced systems like IBM's Watson required significant financial investment and extensive training. Focus training efforts can often be overwhelmed by changes in the environment, such as human boredom with new games or challenges.

Assessing the Global Network: A System as a Single Insect?

The global network of computers collectively might come close to exhibiting near sentience, but the comparison isn't accurate. If humans were to suddenly leave Earth, most of the network would shut down due to power failures. Solar-powered systems with backup batteries might continue, but without a human presence to direct them, they would have no meaningful tasks to perform.

Conclusion: The Future of Sentience

While we have made significant progress in AI, true sentience appears to be a distant dream. Extrapolating from current experience, achieving true sentience for computer systems may require an incomprehensible number of nodes. In the meantime, the quest for near sentience continues, driven by the hope that emergent properties might lead us closer to the subjective experience of intelligence.
