Imagine a world where mobile phones are no longer needed to stay connected, where you can send a message, make a call, browse the web all with a simple thought. This is the vision behind Neuralink, a brain-machine interface being developed by Elon Musk’s company. By directly linking the human brain to digital devices, Neuralink could potentially replace mobile phones offering faster, more accessible communication without need for screens or keyboards. But this technology has raised certain challenges and ethical dilemmas mainly in the domain of security and privacy raising significant questions about the future of human communication and interaction.
