Jaco at 21 had $200 dollars of knack. After 10 years I now have $410 of knack.
so according to my hypothetical math , yes.
Reality: No I'm not as good as Jaco a 21, and may never be.
Also reality: It does not matter, at all, that I am not. What difference should
someone else's ability make to my own efforts?
I'm not saying "talent" does not exist, I'm saying it's a useless factor in
my choices for improving.
But, as I stated, I've learned that "either you have it or you don't" is a very precious idea to many.
It's just not precious to me.
