Game changers in your lifetime that you could not do with out- tools and gizmos

I want to point out that a lot of younger car builders don't know the pleasure of trying to build cars back when I started in the mid-80's....
Finding parts was mail-order, pouring through catalogs, phone calls, junk yards, etc.....
Now I can sit on my couch and shop...click a few buttons and it shows up on my door-step a week later. ....
Game changer for sure.
