Imagine you had a perfect memory - perfect recall ever since birth and an endless capacity for adding new data. Nothing is ever forgotten.

How do you think this would affect your perception of time? How would it affect your emotions - your ability to overcome traumatic experiences frozen in perfect detail and not fixate on past elation/joys and triumphs and live in endless mania? How would it affect your ability to apply meaning, and learn, as well as your ability to navigate contradictions, hypocrisy and paradoxes you've encountered and can perfectly recite at any time, would it make decision making more difficult, knowledge more difficult to attain?

For me the ability to forget is not a flaw of human consciousness, but a necessity. I think the ability to forget is essential for tolerating pain and suffering, to give a sense of progression through time, chronology, and the ability to accept new paradigms and beliefs.

This is the crux of the difference between computers and us. Computers don't forget so long as they have sufficient storage. Perhaps automatic forgetting is a neccesary feature of programming required to give AI more human attributes, but at the cost of being the perfect personal assistant.
