Many scientists remain doubtful that true AI can ever be developed. The operation of the human mind is still little understood, and computer design may remain essentially incapable of analogously duplicating those unknown, complex processes. Various routes are being used in the effort to reach the goal of true AI. One approach is to apply the concept of parallel processing_interlinked and concurrent computer operations. Another is to create networks of experimental computer chips, called silicon neurons, that mimic data_processing functions of brain cells. Using analog technology, the transistors in these chips emulate nerve_cell membranes in order to operate at the speed of neurons.
In the Tell ';n'; Show method of creating effective presentations, you tell you point, then you show it. So, each point requires some validation, some evidence. Which validation you choose may depend on your audience. Some people want hard data, others want to know what the competition is doing, and still others may want the advice of an expert. A story that conveys a poignant situation may be effective. Sometimes, all you need is an image to show what you';re telling. If you say that the copier you sell fits on a small table, a photograph will suffice.
