Elon Musk's Neuralink wants people to control computers with their minds. How close are they?

Neuralink is one step closer to selling brain implants that can transmit human thought. The neurotechnology company in May announced that it had received approval from the U.S. Food and Drug Administration (FDA) to launch its first in-human clinical trial. A statement on its Twitter account said the approval "represents an important first step that will one day allow our technology to help many people." Cofounded by Elon Musk in 2016, Neuralink plans to implant devices in human brains that would allow people with neurological disorders to control computers or robotic limbs with their minds. Musk has said he also wants to "achieve a sort of symbiosis with artificial intelligence" and possibly enable telepathic communication with the device.
