There's only a 100x difference between a dollar and a penny. They're often used together like $4.99. Not the case with bitcoin and sats which have a 100,000,000x difference.
The direction we are headed is the elimination of the term bitcoin. Let's avoid that fate while we are still in the early stages of bitcoin as everyday money.
"Bitcoin" will always be used to refer to the network and the money, even if sats are used everywhere. A single sentence explanation is enough for most people and it's stupid to ret con the definition of a bitcoin over it.
Why avoid that fate? Worked well for Linux. Nobody mentions the L-word. Everyone uses Android.
Bitcoin is already a ubiquitous, great brand. Don't lose it to rebuild another one?
Great brand? Most normal people either think "scam" or "rich white men" right now, which is an improvement from past associations, but still.
In any case, sats doesn't destroy the brand. To the contrary; it augments it.
