I just watched 2 hours of rock videos and not one bass player used his fingers. All pick players I have nothing against pick players I think it looks cool.i play only fingers the only picking I do is my noseI did notice that all of them were under 40 years of age. I guess a new generation thing or they were guitar players at one time
From your opening statement; I just watched 2 hours of rock videos, it's clear the sample of players that generated your question wasn't very diverse.
