Haha, not sure about that, but you most certainly aren't the "majority of professional developers". Neither am I, that's a whole bunch of people who couldn't care less about how you or I want to work.
Professional MacOS developers, before OS X was born, did not use a command line at all, so Photoshop was created by amateurs?
Same applies to developers on Amiga and AtariST, also less professional?
Or what about Windows developers, that hardly bothered with cmd.com, doing their scripting via VBScript/JSCript and everything else via Visual Studio, as it was common practice until PowerShell, with its PowerShell IDE sprung into existence, also a bunch of amateurs?
Don't judge professional developers on other platforms with UNIX glasses on.
