I used to TA undergraduate science courses. I successfully convinced at least one generation of young minds that the SI prefix G is pronounced hard, except for power, where it is pronounced soft like J. I blamed the French for this historical oddity. They bought it.
Giga actually has an acceptable pronunciation with a soft g. The American National Bureau of Standards actually has this pronunciation formalized.
gigga what? gigga who?

You're being downvoted because your comment is inane, off topic, and adds nothing of value to the conversation. Even the grandparent quotation from Back to the Future suffers from the same problem and is being downvoted.
