Medicine is one big area—there are already AI diagnostic solutions which perform better than doctors.
Help desks is another area—there are already low-level AI implementations, but better understanding of natural language should lead to a step change.
All sorts of info-heavy applications:
What is the law on…?
How much would a 15-year loan on this cost?
What's the traffic like on Main St?
What game is most like…?
And on and on.
It's almost limitless. It was AI that figured out that vitamin D helps to prevent severe covid cases. It also mapped out other features of the disease that researchers weren't able to that has helped to develop pharmaceuticals.
And AI is helping Intel and Nvidia to design new GPU's and CPU's and can shorten the process considerably by running simulations. It's going to soon be invaluable in all types of engineering.
The day will soon come when it can do pretty much anything a human can do, only better and faster.
