I took that as like a kid who grew up reading car magazines, but if you threw them behind the wheel would have no real idea what they are doing. I’m thinking of it kind of like fallout 3 where it won’t even let you wear the armor until you find someone willing to give you “power armor training”. Something something “if you don’t know what you’re doing, the armor will snap your bones”.

Also, as someone else said, Maximus is clearly a low-int build, so even if he’s read it, he didn’t retain all of it, lol.
