I described it above. Technology offers options for policy.
Our climate-solving cocktail of 20 years ago involved things like drastic reduction of car use in favour of mass transit, and mass deployment of nuclear power to replace fossil fuel plants. We would be in much better shape today if that was done, but that set of solutions was (and still is) politically untenable - so technologists had (and still have) to invent different solutions, that are easier for politicians to implement.
