Metrics: Success is measured by signal resolution (e.g., number of neurons recorded, currently ~1,000–10,000 for invasive BCIs), latency of response, and user adoption rates (still in early clinical stages, with <100 human subjects by 2025).
Relevance to Noosphere: BCIs could link individual minds to a global digital network, creating a direct interface for the noosphere’s collective intelligence. The GCP’s findings of RNG deviations during collective events suggest that synchronized human attention might amplify such connections, though no direct BCI-GCP link exists.
Challenges: Ethical concerns (e.g., privacy, autonomy), technical limitations (e.g., biocompatibility), and high costs limit scalability.
