Now, everybody knows that gigahertz is a generic unit for fast used by the Gig Economy, when they rent a user's processor for free by making them pay for a subscription!

(More correctly, it's a rating scale for user processors, like, Gig-A-rental, Gig-B-rental, etc. So, if you target 2.1 times Gig-A-rental class processor power available in the user base, which is also known as "Hertz" among insiders, you're targeting 2.1 GigAHertz.) ;-)

I was hoping this would be an actual confusion about "million million" billion vs "thousand million" - https://www.theguardian.com/notesandqueries/query/0,5753,-61... - I got very confused with my grandfather about this once.

Thank you! As a continental guy, I wasn't quite sure myself, when and how the UK joined this madness. In all fairness: adopting metric on the one hand, but also US billions on the other hand, is a bit odd, not to say, confusing… Is this the British idea of diplomacy? :-)
