Thanks for the paper.  I too am pretty skeptical, although I do think 
they are doing the right thing by having the electrodes there for the 
neurons right from the beginning.  Maybe they provide enough "structure" 
that the neurons can figure something out?

They do say in one of the publicly accessible first pages that the hard 
problem is getting the neural net to share your goals, i.e. say you want 
it to avoid obstacles, how do you train for that?!?

Skory - do you know if there is any audio or video available from the 
talk that you say at CMU?  I'd love to listen to that!
