I would think it was more because it was way simpler to adjust software. People mostly used their own software, they didn&#x27;t have millions of lines of code hanging around (they probably could grep all existing source code in a few hours, if needed), the authors of any software that needed changes all were available, often in the same room, and even if the languages didn&#x27;t change, they would have to update their programs because they made breaking changes to their OSes every day (that may be slightly exaggerated)<p>Also, what language would you switch to on your Unix installation?
