Elon Musk's Neuralink implants coin-sized brain chip in human, aims for thought-controlled devices
• Elon Musk's Neuralink has successfully implanted a coin-sized, wireless brain chip into a human for the first time. It can detect neuron spikes, but details are scarce.
• Neuralink aims to refine brain-computer interface technology to help paralyzed patients at first, but Musk's ultimate goal is "human/AI symbiosis."
• Rival companies like Synchron are also testing similar implanted devices to translate brain signals for paralyzed patients. Achievements so far include tweeting with thoughts and helping a paralyzed man walk.
• Experts are skeptical consumer uses like ordering pizza with thoughts will be possible anytime soon, if ever, citing risks, impracticalities, and variability of brains.
• Musk believes the technology is needed to protect humanity long-term from existential threats of advanced AI, not just to improve consumer products.
