For people in rich nations, the level of consumerism they have been accustomed to their whole lives, has to go. For most people this means no more driving, no more flying, no more eating fancy foods and buying fancy things. People have to live pretty much like hippies.
For people in the rest of the world, the promise of the modern industrial rich age (which is mostly a mirage anyway) has to go.
Pretty much nobody in the world is willing to accept this sacrifice (remember, covid only lasted like two years and public will was/is really strained by the end -- what's needed here is a permanent change), so since this is a hard requirement for any solution, there's no other except treating it like a technical challenge.
