I'd rather learn from a person with scars on their hands, calloused palms, and mileage on their face. The ones that can take a 1911 or M1,Winchester, Ruger, S&W, (or pick one), down to a table full of "pieces" and without even a blink put it together, improve the pieces that may need some TLC, because it doesn't "feel" right, with a 62 year old shop equip. and hand tools, make it "sing" to a playing card at 250 yds. (rifle), and never let you down.....
That's how it used to be. That's how my Grandfather did it, I was too young and stupid to not pick his brain for all he knew..
If more of that mindset and exp. was in today's industries, we would be better a better country, not buying Toyota's. (not that I'm bashing Toyota,,, my Tacoma was an awesome truck.)
