Again, when you have no idea how much the command line can do, and the instructions is literally for something as basic as installing Steam, nobody would expect to nuke their DE.

You're also expecting that people should be able to parse an long ass message full of technical terms that they are unfamiliar with the first time they see it.

You guys really overestimate how competent the average person is. Linus was playing the perfect role of a "knows just enough to be dangerous" noob.
