Neurotechnology, Elon Musk and the goal of human enhancement

Brain-computer interfaces could change the way people think, soldiers fight and Alzheimer's is treated. But are we in control of the ethical ramifications?

At the World Government Summit in Dubai in February, Tesla and SpaceX chief executive Elon Musk said that people would need to become cyborgs to be relevant in an artificial intelligence age. He said that a "merger of biological intelligence and machine intelligence" would be necessary to ensure we stay economically valuable.

Soon afterwards, the serial entrepreneur created Neuralink, with the intention of connecting computers directly to human brains. He wants to do this using "neural lace" technology - implanting tiny electrodes into the brain for direct computing capabilities.
