It includes several quotes about the idea that memories are stored physically in the brain and recent research that could allow editing and improving human memory. One quote imagines being able to scroll through memories like photos and perfectly recall everything ever learned. The document also mentions work on developing a service called Memoral that would allow viewing old memories on demand, including scent and sound memories, and accessing all memories as long-term recollections.
