The politics aspect is much more driven by identity and social group than by sunk cost or refusal to have buyer’s remorse. A singular respected leader can turn the ship - churches and pastors were critical in the US civil rights movement, for example - but groups can be more nebulous without a particular leadership structure, like how difficult it is for people to leave Twitter: even though most users agree the experience has significantly degraded, there is no critical mass agreed on a replacement.
The more nebulous groups can break up - Twitter’s engagement is declining - it’s just slow. Maybe years or decades slow to get to the point it’s no longer one of the dominant social media. So I guess keeping the social connections open (giving someone who wants to make a major change an option to still have a friend or family member who will talk to them after), and patience.
Apparently she started out saying AI, then switched to A1 mid-statement. Might have been corrected privately before, but it only partially took.
