Right, in the limit of infinite training, this approach will learn exactly 
what we want it to learn.  Theoretical sufficiency is not generally of 
interest to engineers trying to build systems that solve real problems.

Reinforcement learning is a good tool for learning something, when *all 
you have* is a value function.  It is, however, only a small part of our 
ways to have computers learn to be intelligent.

For example, how do you learn to not get hit by a car?  Hopefully your AI 
will have something better than *only* reinforcement learning.

) Can you explain what you mean by a value function?
) If "success" or "failure" are sufficient value functions (and I think
