How about those of us who didn’t have dads to teach us stuff and so have to rely on YouTube? my grandfather (both) passed when I was pretty young, and my dad went MIA around the same time. Therefore, YouTube has taught me a lot. I do all my own mechanic work on my Jeep, I help my sister with her car, I help my mom with stuff around the house, i work on big marine diesel engines for a living, and honestly, without YouTube, I wouldn’t know 1/2 the stuff I do because I never had anyone to ask or show me. I learned to weld from YouTube, I learned how to deal with computer issues on engines from YouTube, heck, I rebuilt my Jeep engine partially off YouTube. Don’t knock the tube, for someone like me, it’s the best thing since sliced bread.
