I've only played partially for about a few years and I can find most of the notes with my eyes closed. Then you have people like Steve Vai who are the in the guitar equivalence of magnus carlsen playing blindfold chess with 20+ people at once. Some people just like to yap to write something cool and get a few upvotes I guess.
The legend goes that Steve Vai showed up with a beat up guitar at Joe Satriani's place to get lessons from him . Satriani told him to come back after a week with all the notes memorized or he won't accept him as a student. Steve did as he was told and the rest is history.
So yeah, some of us are Steve Vais and others like me take months to learn it. To each their own.
