You mean losing memory over time? Not in my case. I switched from doing things in memory to keeping a notebook at the ripe old age of 24. For two reasons.
The first is that I simply couldn't hold everything in my head anymore because I had to track 5-10 different projects at any time, and context switching without something written down sucks when you have to context switch multiple times a day.
The second is that writing things down was a great way to force myself to clarify my thinking. I became more articulate across the board, not because I got better at bullshitting, but because I was now reserving time in advance to think through open issues in a structured way.
