How likely is it that we live in a simulation? Are virtual worlds real?

In this first episode of the 2nd Series we delve into the fascinating topic of virtual reality simulations and the extraordinary possibility that our universe is itself a simulation. For thousands of years some mystical traditions have maintained that the physical world and our separated ‘selves’ are an illusion, and now, only with the development of our own computer simulations and virtual worlds have scientists and philosophers begun to assess the statistical probabilities that our shared reality could in fact be some kind of representation rather than a physical place.
As we become more open to these possibilities, other difficult questions start to come into focus. How can we create a common language to talk about matter and energy, that bridges the simulated and simulating worlds. Who could have created such a simulation? Could it be an artificial intelligence rather than a biological or conscious being? Do we have ethical obligations to the virtual beings we interact with in our virtual worlds and to what extent are those beings and worlds ‘real’? The list is long and mind bending.

Fortunately, to untangle our thoughts on this, we have one of the best known philosophers of all things mind bending in the world, Dr. David Chalmers; who has just released a book ‘Reality+: virtual worlds and the problems of philosophy’ about this very topic. Dr. Chalmers is an Australian philosopher and cognitive scientist specialising in the areas of philosophy of mind and philosophy of language. He is a Professor of Philosophy and Neuroscience at New York University, as well as co-director of NYU’s Center for Mind, Brain and Consciousness. He’s the founder of the ‘Towards a Science of Consciousness Conference’ at which he coined the term in 1994 The Hard Problem of Consciousness, kicking off a renaissance in consciousness studies, which has been increasing in popularity and research output ever since.

In this enlightening episode, we delve into groundbreaking research that challenges our understanding of the brain’s building blocks. Recent studies reveal that a single neuron possesses computational capabilities rivaling those of entire artificial neural networks, suggesting that each neuron may function as a complex processor in its own right.

This UPSC Podcast explores how learning in the brain is more complex than previously thought, revealing that synapses, the connections between neurons, don’t all follow the same rules. A recent study observed these tiny junctions in mice, discovering that their behavior depends on their location on a neuron’s branches called dendrites. Some synapses prioritize local connections, while others form longer circuits, indicating that different parts of a single neuron perform distinct computations, potentially explaining how the brain forms memories, including during processes like offline learning. This research offers a new perspective on how the brain encodes information and could potentially inspire more sophisticated AI methods.

Recent rapid progress in artificial intelligence has prompted renewed interest in the possibility of consciousness in artificial systems. This talk argues that this question forces us to confront troubling methodological challenges for consciousness science. The surprising capabilities of large language models provide reason to think that many, if not all, cognitive capabilities will soon be within reach of artificial systems. However, these advancements do not help us resolve strictly metaphysical questions concerning substrate-independence, multiple realizability, or the connection between consciousness and life. Ultimately, I suggest that these questions are likely to be settled not by philosophical argument or scientific experimentation, but by patterns of interactions between humans and machines. As we form valuable and affectively-laden relationships with ever more intelligent machines, it will become progressively harder to treat them as non-conscious entities. Whether this shift will amount to a vindication of AI consciousness or a form of mass delusion remains far from obvious.

“Metaphysical Experiments: Physics and the Invention of the Universe” by Bjørn Ekeberg Book Link: https://amzn.to/4imNNk5

“Metaphysical Experiments, Physics and the Invention of the Universe,” explores the intricate relationship between physics and metaphysics, arguing that fundamental metaphysical assumptions profoundly shape scientific inquiry, particularly in cosmology. The author examines historical developments from Galileo and Newton to modern cosmology and particle physics, highlighting how theoretical frameworks and experimental practices are intertwined with philosophical commitments about the nature of reality. The text critiques the uncritical acceptance of mathematical universality in contemporary physics, suggesting that cosmology’s reliance on hypological and metalogical reasoning reveals a deep-seated faith rather than pure empirical validation. Ultimately, the book questions the limits and implications of a science that strives for universal mathematical truth while potentially overlooking its own inherent complexities and metaphysical underpinnings. Chapter summaries:
- Cosmology in the Cave: This chapter examines the Large Hadron Collider (LHC) in Geneva to explore the metaphysics involved in the pursuit of a “Theory of Everything” linking subatomic physics to cosmology.
- Of God and Nature: This chapter delves into the seventeenth century to analyze the invention of the universe as a concept alongside the first telescope, considering the roles of Galileo, Descartes, and Spinoza.
- Probability and Proliferation: This chapter investigates the nineteenth-century shift in physics with the rise of probabilistic reasoning and the scientific invention of the particle, focusing on figures like Maxwell and Planck.
- Metaphysics with a Big Bang: This chapter discusses the twentieth-century emergence of scientific cosmology and the big bang theory, shaped by large-scale science projects and the ideas of Einstein and Hawking.
- Conclusion: This final section questions the significance of large-scale experiments like the JWST as metaphysical explorations and reflects on our contemporary scientific relationship with the cosmos.
