HIGHLIGHTS:

1. Forgetting is not the opposite of remembering; forgetting is a critical process of deep learning.
2. Forgetting often enable deeper learning, and learning or recalling some things contributes to forgetting other things.  
3. Forgetting, remembering and learning have a symbiotic, interdependent relationship

2. Regarding Solomon Shereshvsky: Maybe he didn’t exactly have perfect recall, as this New Yorker article points out, but you get the point of why forgetting isn’t necessarily a bad thing. Here’s another article on people who can’t forget, highly superior autobiographical memory, or HSAM.
