Despite Elon being insane, the idea of brain-computer interfaces could be really great. I’m thinking of people with disabilities or debilitating injuries. This could enable prosthetics with full dexterity that you can control. It could be life changing for some people.

I don’t know if that is the first thing Elon is aiming for, but any breakthroughs in the technology that could lead to it becoming a legitimate option to improve people’s lives, I think would be a good thing.
