The phrase "Tibiwangzi" (Character amnesia) was popular long before the digital age. Back when I was a child in the 90s, middle-aged and old people often found themselves unable to recall specific characters.
I somehow kept the habit of handwriting for years. But as a guy in my early 30s, I do notice characters fade away from my brain from time to time, which wasn't a thing at all in the 20s. And to my surprise, some of the characters are fairly frequently used - I was just completely stuck when I was trying to recall them.
Probably that's how brains and organs peaked and will slowly break down over the following decades just like hard drives.
