"Giga" was considered to sound silly until it became common and we no longer care. "Yotta" sounds silly (to me) now.

Yes, 2**10 times this, yes.

Call me calcitrant, reactionary, or whatever, but I will not say kibibyte out loud. It's a dumb word and I'm not using it. It was a horrible choice.

When I read "KiB" I say "kib" and it's fine. Similar for GiB, TiB, PiB.

"I bought a two tib SSD."

"I just want to serve five pibs."

Actually, it sounds very serious and appropriate.

"mebi" and "gibi" aren't any better, last one in particular if you say it as "jibby-bytes"

Does it really matter if it sounds silly?
