It is actually saddening.
wel-l-l-l-l-lll ....... if you're a performing/session player getting older it's a godsend actually.
I can't imagine I'd work as much at my age as I do if there were a lot of young, pretty people that can do what I do.
There will always be talented young players but that ability to instantly play anything comes from ear training and experience and a lot of that comes from having to learn everything by ear.
But in todays' world of internet available tabs, that's not the method most choose for learning songs since it's so much easier to go look up the tab.
SO I see young players that can blaze and make you gasp at their chops, but couldn't play something without knowing the song to save their lives ..... it's sorta similar to some classical players who mostly read everything they play.
I remember once in Baton Rouge at a 'Phil Brady's World Famous Blues Jam' ..... lol ..... it's a freakin' blues jam with the same 3 chord blues songs as every other blues jam.
Anyway there was this trumpet player who was first chair with the Baton Rouge Symphony so you know he had chops. But after watching players jump up and just play he asked me, "How do they know where to go?"

It was a 3 chord BLUES freakin' song!!
I see that quite a bit ..... a young player might get up and call his 4 or 5 songs and do them and sound good so he gets invited to stay but has a hard time with it.
Even though it's just
another blues song with maybe an extra minor second in it ..... for him it's an entirely different song. He learned the other ones ..... didn't learn
this one.
Thank God really, I gots to work 'till I fall over dead so I like the competition being limited in numbers. That way I'm always in the hunt for gigs.
Rambling here ....... anyways, the skill level overall does seem to be in decline with some exceptions .......
