Isn't this ideological though? The economy can definitely survive without growth, if we change from the idea that a human's existence needs to be justified by labor and move away from a capitalist mode of organization.

Of course if you're a gross commie I'm sure you'd agree since AI, like any other mean of production, will remain first and foremost a tool in the hands of the dominant class, and while using AI for emancipation is possible, it won't happen naturally through the free market.
