I don't think the issue is just allowing proprietary IDEs to interface with Gcc; I think there are deeper issues at play.

Also, I wouldn't say that he's forcing anyone to chop things, he's more likely saying "let's make dishes from recipes which don't require chopping things", but his cooks are still used to chopping. Is there really an alternative to strong "intellisense" and refactoring abilities in IDEs for efficient development ? I don't know. I personally feels that this is a necessary step. Maybe RMS, with his experience of AI research (iirc), has a different view.
