It doesn't help the SI purists who insist we all do mental arithmetic to 8 decimal places, but I am sure their days are 'numbered'.
The fact that the whole world except the US (and a few other countries) use the SI system surely means their days are numbered. Totally. Like, why aren't we all reversing to the Imperial system right now?
You have no idea of what we are talking about. Moving the decimal point is not the same as 'reversing' to an imperial system. Surely that's a very elementary concept?
In the bitcoin context, the 'SI purists" insist on the decimal point staying where it is, forcing everyone to deal with currency to 8 decimal places, making daily mental arithmetic impractical.
The 'bits' advocates want the decimal place moved 6 places right to a more standardised currency convention and format, it works better with financial software, and more importantly it better suits how our brains have evolved in dealing with 'counting numbers', it helps bridge bitcoins usability chasm. Having moved the decimal place, SI can operate as per normal. It's still a decimal system. It still has a decimal place.
Not only that but behind the user-interface level, the 'SI purists' can talk to each other in micro or milli all day long if they wish, so they have nothing to lose, and everything to gain.
