This seems to me akin to saying that: because learning how to use a tool is never research (the tool is already built) it is therefore bullshit and a waste of time. I like the command line so I'm biased in this direction but you need to know your tools in order to do work. What if a mechanic didn't want to deal with all that "how-to-use-a-wrench" bullshit and just wanted to fix things!
