Elon Musk’s vision of the future takes another step forward

A pig now has one of his implants in its brain

IN IDLE MOMENTS, people sometimes dream about the future. Of cars that can drive themselves. Of travelling to other planets. Of moving objects by the power of thought. Whichever particular dream you have, though, Elon Musk is probably trying to make it real. Self-driving cars and travel to Mars are the provinces of two of his firms, Tesla and SpaceX respectively. Moving objects by the power of thought is the province of a third, Neuralink. And on August 28th, at a presentation broadcast over the internet, Mr Musk showed off the firm’s progress. The highlight was the appearance of Gertrude, a pig with a chip implanted into her brain.
