Brain-computer interfaces (BCIs) are technologies that enable direct communication between the brain and computers, bypassing traditional input devices like keyboards or mouse. BCIs have a huge potential for tech company investments because they could completely change how we interact with technology. BCIs can be utilized for immersive gaming and entertainment as well as for medical applications like helping paralyzed people regain movement. Investments in BCI technology by tech businesses have the potential to give them a major competitive edge in these and other areas. The potential for BCIs to influence how we engage with technology in the future is endless as technology develops.
