While having a good memory is important for cognition, it is just as important to be able to forget memories. There are probably limits to how efficiently our brains can scan memories for information relevant to a given situation and having more memories decreases the efficiency of this process. Also, when you can find almost all knowledge about anything on Google in just a heartbeat, it's inefficient to try to memorize most things. As Einstein said, "Never memorize what you can look up in books."
