It’s not cursed, it’s just a different way of grouping. Nothing about grouping in multiples of 10³ is a more natural grouping, were just more used to it.

And I’m pointing out how metric prefixes are actually euro-centric, and that’s annoying for them. But there’s nothing fundamentally worse about breaking digits in groups of 4, rather than 3

1,000,000,000,000 = 1,0000,0000,0000 (10^12^) [Meme of black and white muscular arms embracing.]

Look up the indian system, now that’s actually cursed.
