I smoked for almost 10 years. I really regret that. Thankfully, I came out on the other side. I hope my lungs are repairing themselves now.

As computer intelligence gets better, what will be possible when we interface our brains with computers? It might sound scary, but early evidence suggests otherwise: interfacing brains with machines can be helpful in treating traumatic brain injury, repairing spinal cord damage, and countless other applications.

Successful technologies often begin as hobbies. Jacques Cousteau invented scuba diving because he enjoyed exploring caves. The Wright brothers invented flying as a relief from the monotony of their normal business of selling and repairing bicycles.

At 13 I realized that I could fix anything electronic. It was amazing I could just do it. I started a business repairing radios. It grew to be one of the largest in Philadelphia.
