Why AI is Hard
First I propose to give some attention to reasons why the problem of engineering intelligence is a difficult one to solve, introducing the "intelligence as hologram" analogy.
Cutting out Inessential Capability
Then the idea that Aritificial Intelligence is the simulation of the human brain is taken as a starting point for a process of whittling down.
In this process aspects of the function of the human brain are considered and speculations are made about which of these could be dispensed (in the manner of bath water) with without our losing hope that intelligence will remain (in the manner of the baby).
Delivering Capability without Intelligence
A third process is then entered into, in which we consider the core capabilities required for our artificial intelligence and see how best to deliver these without solving the problem of Artificial Intelligence.
