AI is really exciting. A computer system modeled after the human brain and nervous system detects neural connectivity issues in the human brain and nervous system brought on by Alzheimers. And, we are just scratching the surface of this technology. I believe the pace and acceleration of innovation for AI will be like nothing we've seen before. At some point, and we have seen a little bit of this already, it will basically build and enhance itself. This may become an arms race of corporations and countries having the largest neural networks. At first, these networks will be aggressively learning and making themselves more intelligent by modifying themselves.
