To Keep Track of World's Data, You'll Need More Than a Yottabyte (wsj.com)
An anonymous reader shares a report: In 10 or 15 years, Dr. Brown, who is head of metrology at the National Physical Laboratory in the U.K., anticipates the amount of computerized data worldwide will exceed 1 yottabyte in size, and without expanding the list of prefixes, there will be no way to talk about the next great chunk of numbers. Even worse, dilettantes could fill the void by popularizing glib prefixes such as bronto or hella -- terms that have already won fans. Without professional intervention, Dr. Brown fears, the next numerical prefix could become the Boaty McBoatface of weights and measures.
[...] For the record, there is an argument to be made for adopting a prefix like bronto: giga and tera are based on the Greek words for "giant" and "monstrous." Why not make bronto, named for the brontosaurus, official, perhaps along with tyranno, stego, colosso or even yeti? Dr. Brown is sympathetic to the argument but unconvinced. Instead, he proposes four prefixes that adhere to recent naming conventions [Editor's note: the link may be paywalled; an alternative source was not available.]: ronna and quecca for octillion (27 zeros) and nonillion (30 zeros), along with ronto and quecto for their fractional counterparts, octillionth and nonillionth. Like the latest sanctioned prefixes, Dr. Brown's proposals are loosely related to Latin and Greek words for numbers (in this case, nine and 10). And like most of the prefixes, his suggestions end in "a" or "o." But the process of expanding, or even amending, the official measurements is lengthy.

They're not.
they're making new prefixes for every third power of 10.
If a consensus isn't reached relatively soon, the whole "billion" thing will happen again. it's been defined as both 10 to the 9th power and 12th power.
It has always seemed a bit arbitrary to label something as "the world's data".
A yottabyte is 1e24. That is more than 100 terabytes per human.
You could always add the history of every cache on every processor on the planet to your definition of "data" and have a much larger number.
640 yottabytes ought to be enough for anyone.
