Can't unplug from banking, even when literally communists (literally literally, I've met some proud of being communists, they still got a mortgage).
Coal and petroleum-based fuels are slowly getting unplugged, but the issues were known over a century ago, and the transition only became relevant scale when the alternative was already much cheaper — and it's not yet clear how much damage has been done in the intervening years.

Any AI worth using is so because it's at least one of [cheaper, better] than a human on the same task: any AI which is both more expensive and worse just doesn't have any reason to be used in the first place.
This means that "unplugging" an AI comes with a cost of losing every advantage that made you start using it in the first place.
