High-resolution brain-machine interfaces (BMI), are predictably complicated — they must be able to read neural activity to pick out which groups of neurons are performing which tasks. Neuralink demonstrates its next-generation brain-machine interface. Neuralink’s system will be used to create a “digital super-intelligent [cognitive] layer” that enables humans to “merge” with artificially intelligent software. Millions of neurons could be influenced or written to with a single N1/Link sensor.
