Neuralink patient controls games by thinking during interview
A Neuralink video showing a quadriplegic man controlling a mouse and playing games like chess and Civilization 6 purely by thought sparks both awe and skepticism. Commenters note that brain–computer interfaces and thought-controlled gaming have existed for years, arguing Neuralink’s real novelty lies in aiming for long-term, high-channel-count implants that can both read and write brain signals at scale. Others question the lack of independent verification, raise concerns about safety, privacy, and Elon Musk’s promotional track record, and debate how much this improves on existing assistive technologies such as eye tracking and voice control.
Perceived Significance of the Demo
- Many commenters find the live demo emotionally powerful, especially the patient’s joy at controlling a mouse and playing games like Civilization 6 again.
- Some see it as a potentially historic “breakthrough moment,” others argue the basic capability (brain-driven cursor/game control) has existed for over a decade.
Prior Art & What’s Potentially New
- Multiple posts note that brain–computer interfaces (BCIs) have long enabled cursor control, flight simulators, robotic arms, and commercial gaming headsets.
- The novelty is framed as: more electrodes, higher resolution, implanted long-term, wireless, and aiming to scale beyond small lab trials.
Skepticism and Track Record of Musk Companies
- Several commenters distrust the demo, citing past edited/overstated Tesla FSD videos and other marketing claims as a “track record” of exaggeration or misleading framing.
- Others push back, calling that speculative or irrelevant, and note recent FSD improvements and other engineering achievements.
- There is debate over whether overly aggressive FSD timelines were “lies” versus overly optimistic beliefs; intent is contested.
Medical & Technical Considerations
- Discussion of brain scarring, biocompatibility, and long-term viability: flexible, smaller electrodes are said to reduce, but not eliminate, scarring; “years” of stable use is hoped for but unproven.
- Safety concerns include infection, surgery risk, and the challenge of keeping intracortical implants reliable over time.
- Clarification that this is not EEG on the skull but intracortical wires measuring voltages inside the brain, with potentially ~1000 read/write channels.
- Questions raised about required compute power, latency, and whether the decoding neural nets adapt online to brain plasticity.
Comparison to Existing Assistive Tech
- Some argue similar function could be achieved with eye-gaze, voice control, switches, or non-invasive EEG, without surgery.
- Others counter that eye-tracking is limited (accuracy, “Midas touch” issues, physical ability requirements) and often inferior to a high-bandwidth, always-on implant.
Future Possibilities & Risks
- Speculated paths: controlling exoskeletons or robots, reconnecting spinal cord segments via wireless links, and direct sensory stimulation (vision, hearing, touch, VR).
- Strong concerns about privacy, potential for “ads in your brain,” manipulation, or malware inserting thoughts, given read/write capability.
- Some express willingness to wait many years to see long-term outcomes and independent verification.
