伊隆·马斯克的 Neuralink, 使用人 头部植入物来补偿残疾,，它已成为所谓脑机接口 (BCI) 的典型代表。但一些公司打赌，大众市场的神经技术根本不需要打开头骨。
Elon Musk的 Neuralink, which uses implants in people的 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 的工作原理是处理大脑信号并将其转化为命令,，从而允许外部设备通过思想进行控制。
BCI works by processing brain signals and translating them into commands, allowing external devices to be controlled by thought.
该领域初创公司的资金仅占流入人工智能资本的一小部分。但随着公司不断取得里程碑,，例如使患有包括肌萎缩侧索硬化症(ALS) 在内的退行性疾病患者能够使用大脑信号打字或玩视频游戏，人们对这个新兴领域的兴趣正在上升。
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.
