Musk claims ‘first human brain chip’ implanted – what does it mean for people with neurological conditions?

Imagine a brain implant which could help people who’ve lost the use of their limbs to control a computer keyboard using just the power of thought. Elon Musk’s startup Neuralink claims it’s successfully implanted a chip inside a human brain for the first time, adding that the patient is “recovering well”.

The firm got permission to carry out human clinical trials last year – and set about recruiting patients with quadriplegia to test out the safety and functionality of its device.

We’ve been talking to the American tech guru Jaron Lanier  and started by asking him how far off we are from connecting human brains to machines to help with neurological conditions?
