Can two or more brains be linked together and get synchronized?
If until recently, ideas of this kind belonged to the field of science fiction or were otherwise relegated to mere discussion, today, thanks to projects like Neuralink, we can start talking about them as a real technology that will soon be available. A neural connection between two or a group of individuals might appear absurd at first glance, but in reality, there is already a form of connection between people that we use every day: the internet. Through the internet, we are able to communicate with people all around the world and access information, news, and opinions that we would otherwise not be aware of. A neural connection would be a sort of extension of this connection, allowing us to share our thoughts and feelings directly with others, as if they were our own.
However, a direct synaptic connection might still seem frightening to some, as understanding the thoughts of others could violate their privacy. Nevertheless, one could imagine a voluntary and secured connection, protected by robust security systems, in which only the information chosen to be shared is accessible to others. In this sense, it would be similar to a social network, where individuals have complete control over their personal data that they want to share.
The potential of such technology is vast and would revolutionize the way we interact with each other. Firstly, it would allow us to understand others better and empathize with them. Often, wars and killings are caused by a lack of mutual understanding and the difficulty of seeing things from someone else's perspective. With a neural connection, it would be possible to better understand others' motivations and thoughts, reducing the risk of conflicts. For example, if two peoples are in contrast due to religious, social, or political reasons, thanks to the neural connection, they could better understand each other's beliefs, traditions, and customs, without having to resort to war. This would foster greater empathy and compassion between peoples.
Of course, this is just the tip of the iceberg, and from both a theoretical and practical standpoint, many years of development and experimentation are still necessary. However, it is a fact that, in general, ignoring a technology that, like all discoveries, can be used for both humanitarian and military purposes, would not help improve or protect humanity or biology. It is therefore necessary to delve into, study, and understand these scientific advancements in order to regulate and utilize them in the best possible way.
