I just stumbled upon this article: To Remember, the Brain Must Actively Forget | Quanta Magazine, and it served me as quite a confirmation bias. I always reflected why it is so hard to learn something, or remember something. Consider, what a great super power it would be to remember it all. The true new point of view for me here is the merit of forgetting. If we remembered everything, we would be completely inefficient because our brains would always be swamped with superfluous memories.
