Its fun how people tend to talk about extremes while most people i guess are somewhere in the middle..

Espescially for keyboardists, i guess its important to know some theory..
As well as know how to play some scales in the correct fingering..

But its also important to see and hear how other instrumentalists play..
Not just piano, organ and epiano have different playstyles
But also emulating other instruments or fingerdrumming on the keys requires training,but also a good ear.
