Conclusion

Neuralink is a company with the most ambitious vision and strongest capital in the BCI technology field. Technologically, it boasts the highest level with 1,024-electrode ultra-high-density BCI, fully wireless system, and automated surgical robot. Since the first human implantation in 2024, it has successfully implanted 13 patients as of October 2025, with all patients showing encouraging results such as controlling computers using thoughts alone.

The $1.29B funding and Elon Musk's reputation are powerful assets for long-term R&D and talent recruitment. The multi-product pipeline consisting of Telepathy (motor function), Blindsight (vision restoration), and Deep (Parkinson's disease) targets various medical markets and ultimately aims for the human enhancement market.

However, challenges remain significant. Technical issues like thread retraction, inherent risks of invasive surgery, high initial costs, and lack of long-term safety verification are obstacles to commercialization. Competitors such as Synchron's minimally invasive approach, Blackrock Neurotech's extensive clinical experience, and Precision Neuroscience's reversible system pose real threats to Neuralink.

Regulatory and ethical aspects also face numerous issues including FDA approval uncertainty, brain data privacy, social impacts of cognitive enhancement, and animal testing controversies. Particularly, human enhancement applications for healthy individuals are expected to require considerable time to gain acceptance from regulatory authorities and society.

Neuralink's success depends on clinical trial results over the next 2-3 years, FDA approval acquisition, and commercialization speed compared to competitors. In the short term, focus should be on proving value as a medical device, while the long term will determine whether the innovative vision of human-AI integration can be realized. As the overall BCI market is expected to grow at an average annual rate of 10-18% through 2030, attention is focused on whether Neuralink will lead the market or be overtaken by competitors.
