Ministry for the Future, by Kim Stanley Robinson.
Engagingly and optimistically approaches some deep questions: How might social media be reformed if people owned their attention equity? How would banking need to be reshaped for a decarbonize future? Could you pump the water from under glaciers to slow their slide into the sea? Would geo engineering and eco terrorism play a role?
It’s no Monk and Robot (which I loved). Much darker, but grounded in our reality and hopeful.
