Who says you have to know your grep from your awk to use Linux or *nix for that matter? Robin 'Roblimo' Miller over at NewsForge has been eschewing the command line since 2000. According to Robin, it's now possible to run Linux without knowing any commands besides point-and-click and cut-and-paste. If that's true, then who needs geeks? Bold words to be sure.
What I'm predicting here is exactly what members of the old "Linux should only be for geeks like us" club have always feared: Linux that Sam Sixpack and Polly Pina Colada can use it as thoughtlessly as they use Windows today. It is part of the "World dominates Linux" process, and it is going to happen whether you like it or not.
