While Musk's Neuralink drills into skulls, China's BrainCo bets the future of brain tech is wearable
Interest in brain-computer interfaces is rising as it promises to help people with compromised neural abilities.
Opening excerpt (first ~120 words) tap to expand
Elon Musk's Neuralink, which uses implants in people's heads to compensate for disabilities, has become the poster child for so-called brain-computer interfaces (BCI). But some companies are betting that mass-market neural tech won't require opening the skull at all.BCI works by processing brain signals and translating them into commands, allowing external devices to be controlled by thought. Funding for startups in the field is a fraction of the capital flowing into artificial intelligence. But interest in the nascent field is rising as companies notch up milestones, such as enabling people with degenerative conditions including amyotrophic lateral sclerosis (ALS) to type or play video games using brain signals.AI is a catalyst, boosting signal-processing capabilities.
