Being old, and a guitar player who learned how to play from the Beatles and the other musical groups of the 60's.... yeah I can relate.
I see YouTube videos of kids, posted on Facebook ... both boys and girls who can flat out shred a guitar fretboard. And in the one that comes to mind, the little girl (she looks to be about 12 years of age) is setting there shredding to a Metallica song or some other technically advanced song and not a hint of emotion on her face or in her playing. None.... Just the display of the technical skills and ability to play at a high rate of speed. Perhaps one day she will hear some Santana and that will touch her and she will learn about soul and how to incorporate it into her technical prowess.
I have seen that, and like so many others here, had the proverbial, "I should burn my guitars and quit playing" moment. However, I remember there are guitarists like Carlos Santana, Mark Knoppler, Chet Atkins and so many other really talented and tasteful players. Too many to recall or name. And I want to align myself with that group. The ones who touch the heart and soul of the listener.
Give me a choice between technical shredding and tasteful soul and I'll take the slower, tasteful, emotional playing every time. It may not be fancy and the Metallica crowd would likely find it boring, but it touches the deeper parts of the listener's soul and if it takes them away for that brief moment, it was all worth it.
