Apple's announcement of a sci-fi like brain computing interface shows that the company still has its eye on cutting edge innovation. But it also highlights the challenge weighing on the company's day-to-day business.

Cupertino once again captured imaginations on Tuesday, unveiling a visionary initiative that could one day allow users to command its devices using mere brain signals.

Apple adds support for brain-computer interfaces (BCIs) to iOS, iPadOS, and visionOS. It's currently working with startup Synchron to test it on patients.
