Let me share my own thoughts from another point of view.
I am just a leisure times and quite lazy player.
I turned 64 and collected plenty of songbooks since 1980 or so.
I would always play at sight. Never really sang.
I do not remember learning a song except the "The House of Rising Sun" arpeggios : Who didn't.

Three years ago, I decided to take private fingerstyle lessons.
My coach would allow me to choose a piece to work on.
I began with short one page pieces, staff and tabs.
Believe me, I needed daily work for six weeks to learn that single piece.
OK there were some skills to get, but, I hardly remember the notes !
During my second session, I would hardly learn a two pages piece !

I feared I had some memory problem, but no way : I still can remember
the news, be it on tv or e-newspapers, as well as a conversation I once had
some days, weeks or years ago. My memory is still working quite well.
Though former professional data are slowly going, they come back quite
fast when I read some news touching my former work field.

The good news here is as riding the bicycle, good knowledge always remains.

I had discussed the thing with my coach : I concluded I had no real musical
talent, only work, and my mind refuses to learn notes.
