I notice you ignored my valid point about other terminology which has been changed.
It was a valid point, so it didn't need comment.
It took about 50 years, but it's pretty much a dead term now.
And as others observed herein, if and when these other prefixes become the norm, I and they will adopt them. But in the meantime, they're nothing more than a needless distraction from more important things. Demanding their use actually INCREASES confusion and wastes time, as in "WTF did you say?", when "kilobyte" would have been understood by everyone in the conversation. Even you, if you'll be honest enough to admit it.
Can you cite any examples of where kilo has truly been misunderstood? No one in six pages of this thread has shared such an incident. Why create delay and obfuscation when it's entirely unnecessary?
Edit: The fact that kilo continues to be used, without incident, provides the answer to the question of why kibi et. al haven't "caught on yet". If there was an actual problem, everyone would have adopted them by now. But there is no problem, so folks focus on getting their jobs done. There's a lesson in that.
