You're just used to the common prefixes. Kibi is not any weirder than yotta, pico, or deci. They all sound silly if you think about it - so we just don't.
No, its definitely not silly. Why make comments like this? I'll take the repercussions, but passing judgement on language by how things sound is doodoo behavior.
Not really. It's important for introduced language to sound appealing and appropriate for its use, or it will fail to catch on. If Apple has called the iPhone the gibiFon it'd have been far less likely to turn into the success it was.
Do you not remember all the people making fun of eye-phone? And all the sanitary pad memes for iPad? There were so many people who thought those were silly - they got over it with time.
