The thing I'm most excited for is the removal of FUD from our daily lives. Everything on our would is designed around the preconceived notions of a small group of people from the past.
You can see this most obviously in traffic and urban planning. They had limited technology and time to make decisions 100 years ago that have serious negative affects today.
AI will soon be able to run its own complex models and decisions can be fact based, rather than emotional.
