What scientific purpose do you think EyeWire serves?

A general question - I’m curious about your perspective on the science of EyeWire.

1. To map the neurons and cell of the eye.  To learn how they (parts we map) interact. Also hopefully, could then help to understand the brain.

2. Learn how we as players act; thus improve the ability to use our amateur time/skills to make a difference.
[Motivation - for me,I want to use my time to make a difference] 

Using cheap labor to teach the AI how to do a better job. Hopefully it will lead to useful knowledge and better health for man.
