You don't have to be a wizard, just competent.

if you want to compare yourself to someone competent with an IDE, you better be a wizard

I think you're overestimating the difficulty of developing on the command line.

I'm really not. I've done both. IDEs were created because they make it more efficient to write code, do you really think this whole line of technological development was a mistake? Even a 10-20% decrease in time on average is huge.

I think they were originally created for environments like Windows where the basic development tools weren't part of a normal operating system install.

I have no idea of why they were created, Windows certainly was the front-runner for GUI stuff. I worked at my first job doing java dev with emacs and I've been fully working on linux for the last several years and I still find eclipse to be superior. Maybe it is because the learning curve is lower and my emacs environment was never setup properly, but I think the OSGi framework (dependency management standard in eclipse) is genuinely useful and I love having everything I need in one program. I still find myself writing sed/awk/bash scripts occasionally, but my workflow in my IDE with mylyn integrated to bugzilla and SVN is just so much faster...
