从恢复视力到重塑大脑：神经接口如何降低人类的脆弱性

PRIMA's European marketing approval turns a retinal prosthesis from a speculative moonshot into a product that can begin serving paying patients.

When the optic nerve remains intact, stimulating the retina offers a more tractable path to restoring vision than intervening deeper in the thalamus or visual cortex.

Neural devices can produce an engineering improvement curve because field of view, grayscale, color, and resolution can be upgraded step by step after an initial proof of function.

Treating the brain as a literal computational system enables direct functional interventions that can yield larger and more immediate effects than many molecular therapies.

Brain-computer interfaces form a category as broad as pharmaceuticals, spanning assistive communication, sensory restoration, motor control, and deeper changes to the boundaries of the self.

People may accept substantial changes to identity when phenomenal continuity is preserved, while an exact software copy may still fail to feel like personal survival.

The Platonic representation hypothesis suggests that large AI models and biological brains may organize concepts with similar geometry because both are capturing structure in the same underlying data.

AI models can serve as unusually accessible experimental systems for neuroscience because their representations are easier to inspect and perturb than living brains.

A durable neurotechnology program needs a credible path to revenue because near-term clinical products finance the longer research required for biohybrid interfaces and broader medicine.

Science's long-term ambition is to reduce human fragility by repairing, replacing, and eventually upgrading biological components while preserving the continuity of the person.
