Is a conscious silicon brain achievable?

Abstract

The biological mind is created by brain activity, and the mind's experiences and thoughts can change its structure and function. To construct a digital twin brain, it is possible to decode the unique activity of the human brain for each of the mental faculties responsible for all mental phenomena, create their digital twins, and connect them to the reconstructed and simulated neural circuits of human brain. Another strategy is to reconstruct and simulate the neural circuits of functional human brain organoids individually and in assembloids to match the functional characteristics of neural circuits through iterative simulations and experiments, and combine them with artificial intelligence (AI) to create a kind of silicon brain. Then, with the convergence of silicon brain technologies, AI avatars, the source of embodied sense data, and metaverse, the source of environmental sense data, a complex system can be created that may represent a level of consciousness. The first approach faces major issues in data acquisition, computational requirements, and the integration of diverse data sources. The second approach is a practical solution that can be achieved very quickly and can be really effective in addressing the challenges of the first approach. Building a silicon brain will increase our understanding of the mechanisms behind mind and the functioning of consciousness. This will improve brain models and will have many applications, mainly useful for achieving better progress in medical science.
