Oh come on, not that "Vim/Emacs vs IDEs" crap again. Please stop 
being so black&white and pretentious. Have you ever tried 
IntelliJ IDEA? It's the best IDE I know, and it saves me a lot of 
time by automating tasks I'm not interested in, e.g. reindenting 
the code, maintaining project files in Git, renaming things 
within their contexts etc., while proving an excellent debugger, 
a decent unit test runner and and integrated lint. I spend much 
less time messing with these things and have more time for 
actually writing the code and experimenting.

If you consider all these conveniences unnecessary, good for you. 
You can continue using your favorite screwdriver, but most 
professionals prefer a screw gun, because it saves time. You may 
have big powerful hands, but you don't have to brag about it and 
point fingers: "Just look at this pussy with a screw gun, he 
clearly has never been to gym." By the way, it's perfectly normal 
to make screws that hold things tight, but not easily screwed in 
by hand.
