Neuralink celebrates one year since implanting their first telepathy device, the N1 Link, in a human. The blog post highlights the ongoing PRIME Study, which is evaluating the safety and efficacy of the N1 Link and the R1 surgical robot. The primary goal is to enable people with paralysis to control external devices with their thoughts. Early progress has allowed a participant to control a computer cursor, demonstrating the potential of this technology to restore independence and improve quality of life for those with severe disabilities. The post emphasizes Neuralink's commitment to patient safety and expresses optimism about the future of brain-computer interfaces.
A Parkinson's patient in the UK reports feeling "cured" after receiving an adaptive deep brain stimulation (DBS) device. Unlike traditional DBS which delivers constant electrical pulses, this new device monitors brain activity and adjusts stimulation accordingly in real time. Tony Howells, diagnosed 15 years ago, experienced significant improvement in his tremors and mobility after the device was implanted, allowing him to return to activities like gardening and playing golf. While researchers caution against using the word "cure," the adaptive DBS technology shows promise for personalized and more effective treatment of Parkinson's disease.
HN commenters discuss the exciting potential of adaptive DBS for Parkinson's, but also express caution. Some highlight the small sample size and early stage of the research, emphasizing the need for larger, longer-term studies. Others question the definition of "cured," pointing out that the device manages symptoms rather than addressing the underlying disease. Several commenters delve into the technical aspects of adaptive DBS, comparing it to previous open-loop systems and speculating on future improvements in battery life and personalization. A few share personal anecdotes about family members with Parkinson's, expressing hope for this technology. Finally, some raise concerns about the cost and accessibility of such advanced treatments.

Hacker News users expressed significant skepticism regarding Neuralink's "telepathy" claims. Many commenters argued that the technology demonstrated is simply a brain-computer interface (BCI) controlling a cursor, not actual telepathy. They pointed out that similar technology has existed for decades, albeit less refined. Some questioned the scientific rigor and long-term viability of the implant, citing potential issues with biocompatibility and the necessity of frequent upgrades. Others discussed the ethical implications, particularly concerning privacy and potential misuse of the technology. A few commenters acknowledged the potential benefits for disabled individuals, while remaining cautious about overhyped marketing and the long road to practical application.
The Hacker News post "A Year of Telepathy," linking to a Neuralink blog post, has generated a number of comments discussing the ethical implications, technological feasibility, and potential future of brain-computer interfaces (BCIs).
Several commenters express skepticism about Neuralink's claims and timeline, questioning the actual capabilities of the implant demonstrated and highlighting the significant challenges that remain in achieving true "telepathy." They point out that decoding neural signals related to intended movements is considerably different from reading thoughts or complex intentions. Some also raise concerns about the long-term effects of implanting such devices, including potential health risks and the need for ongoing maintenance or replacements.
The discussion delves into the potential societal impact of BCIs. Some users imagine positive applications, such as restoring lost function for individuals with disabilities, treating neurological conditions, or enhancing human capabilities. Others express apprehension about the potential for misuse, including privacy violations, manipulation, and exacerbating existing social inequalities. The idea of BCIs potentially creating a "two-tiered" society is touched upon, with those who can afford and access the technology having a significant advantage over those who cannot.
A few commenters raise the philosophical implications of BCIs and what it means to be human. They discuss the potential blurring of the lines between biological and artificial intelligence, and the possibility of fundamental changes to human consciousness and identity.
The ethical implications of animal testing in the development of BCIs are also debated. Some users express strong opposition to the use of animals in such research, while others argue that the potential benefits for humans justify the practice, provided ethical guidelines are strictly followed.
While some commenters express excitement about the potential of this technology, others urge caution and emphasize the importance of responsible development and regulation. The discussion reflects a mix of hope, skepticism, and concern about the future of BCIs and their potential impact on society. There's also some discussion about the regulatory hurdles Neuralink faces and the difficulty in translating research findings into safe and effective products for widespread human use. Several users question the company's PR strategy and express frustration with the lack of detailed scientific publications.
