I have not memorized a phone number that was not my wife’s or kids’ in 10 years. I don’t think that makes us less human. We have evolved to do this. What we do need to do, though, is to be more attuned and more sensible about what things we offload and what things we don’t. We are, in a real sense, the sum total of our memories. The human task of understanding yourself is one that requires being able to think back and construct sensible stories.
