Interestingly you should mention this - I don't think I've ever quite discussed it with anyone.
I've been experiencing something similar for the last few years. It's the years where I have expanded the most, and have been living much more in the now than I've ever done before.
As opposed to my twenties for example where my memory was very sharp and where I was very much living in my head.
I don't see this as as loss at all in the same way I don't see letting go of stuff I don't need as a loss. As you, I experience that my world and my life is amazing and my joy expanding. Also, whenever I need any information I have immediate access to it.
I suppose that if I wanted to dwell in memories of the past I could, but why would I? I have lived my past and now it's just stories. I prefer living and playing with the stories that unfold right now.
A funny byproduct of this "memory relief" is that I can watch a movie that I know I've seen before (maybe not last week, but say last year) almost as if I've never seen it before. I don't remember the plot, I don't remember the ending, I don't remember the lines. So it's like watching a completely new movie. Which in fact it is, as I'm changing all the time and the person that's watching the movie now is not the same person that's been watching it previously.
