Importance of Environments
   - The environment is really important to the idea of CABot.
 
   - I also think that it's really important to developing real
       AI.
 
   - People learn things from the environment.  
 
   - We need to have our systems in relatively complex environments,
       and learning from those environments.
 
   - This seems like a strong requirment to get real AI.
 
   - This is intimately related to the symbol grounding problem.
 
   - Instead of being programmed, the system learns from the environment.
       This should make agents more fun to play with and against.
 
   - It also has other obvious advantages with intelligent assistants.
 
   - Big world small brain.  People (and agents) have small brains but
       need to cope with a big world.
