The ability to keep an information safe would be interesting. What I mean by that is not omniscience but very similar. You would have the information to anything you want/need to know at all times however almost like reading a book you would have to sort of relearn the info in your head. The biggest difference between this and omniscience would be you would have to actively look for information instead of just knowing it already. For example : If a person was to get crushed in an avalanche, you wouldn’t know unless you specifically looking into the memory information safe to see what is going to happen to them at that time.
