Neuralink patient controls games by thinking during interview

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.
