Why Does Neuralink Start With People Who Have Disabilities?

Neuralink starts with people who have disabilities because there is some risk with new technology, so the reward has to be really high. Elon Musk gives the examples of being able to use a phone versus not being able to use a phone, and being able to walk versus not being able to walk.

Elon Musk says Neuralink could later treat extreme depression or morbid obesity, including cases where people died at age 35, by changing a setting in the brain that controls hunger.
