customer service, and creative work.
Virtual and augmented reality (VR/AR): Immersive
communication in virtual spaces (e.g., VR meetings,
metaverse).
Brain-computer interfaces (under development): Potential
for direct thought-based communication.
Impact: Communication may become instant, seamless, and
integrated with human cognition.
