There are many programmers who resist learning another language because it's different than what they originally learned. I believe pg himself wrote an essay about that once. There are absolutely blub video editors.

FCPX might be a good tool for a small time editor that needs an occasional video, but it is not up to professional standards yet.

There are plenty of valid criticisms of FCPX, but this stuff is nonsense: there are plenty of professional editors using it already.
