Numbers go into a system, numbers come out of a system, and we make decisions based on that. There's problems with agreeing on the input, like you said. Then there's a problem with determining action based on output from the operations, because inevitably decisions will be outsourced and the people using the machine output won't know how it works, know it's limitations. That's effectively magic, and I get antsy whenever people won't have a fundamental grasp of how a piece of tech works but will be using it, especially using it to make decisions.
Any thoughts on how you resolve any of these?
