Each of the above systems is based on its own ideas and the authors seem to do little but criticize other approaches to the problem rather than admit that another approach lends something useful to the AI as a whole. Alife seems like a promising prospect, but at the expense of time. To speed up its development requires pure computational power. This would best be approached by support of the proposal for an artificial life reserve. Neural networks similarly are a viable prospect, but again at the expense of computational power.
Intelligent agents have far to go to demonstrate any intelligence.
Parsing AIs like Colin and Eliza are great to talk to, but like intelligent agents, they lack any real intelligence. Even worse, they have very little data to go by. Finally, the great 20 year CYC project, which many believe holds the greatest prospect for a tangible AI, must be spoon-fed information on a daily basis. The basic search algorithms located in intelligent agents and the front end of Colin or Eliza to communicate with humans, or more spectacularly, each other. Finally, it could be given emotions, which would aid it, just as human emotions such as motivation increase our performance.
