Some potential uses for neural networks are rather futuristic. Right now, many computer systems can recognize the IP address of a machine and so moving offices does not generally create trouble for LAN connections. However, if your computer were able to recognize who was using it (and similarly for the telephone), a whole degree of anonymity would vanish. This might not be what we want. On the other hand, computer assessment of its user's state of knowledge might be exceptionally valuable for systems designed to handle, say, building security. Fire, or some other life-threatening emergency, can reduce a normally competent person to hysteria, while indeed the guards might be incapacitated and it might be necessary for a passerby to initiate some complex procedure. The problem is not just the pattern recognition task, which (though formidable) seems within reach, especially by neural network. It is the embedding within an ``intelligent'' system (i.e., the AI of it) which appears to be the key obstacle.
