Sometimes I just like to have a leg up. I got Starfield a week or so after it was officially released and before I got it I watched a couple "10 things I wish I knew before I started playing" type videos. Made the game more enjoyable for me instead of learning it the hard way.
Starfield is one of the few games that I would actually really recommend people watch a few of those before playing. Like most skills are nearly worthless or at very least the game doesn't represent what they do properly.
