Issue Scenario A 'Harmonious Prosperity': AI harmony, halted warming and a second globalisation by 2050

Summary

Scenario A combines human-AI harmony, a halted temperature rise and a second globalisation, and had zero inconsistency in the cross-impact balance analysis. AI develops in step with society and reaches an early stage of artificial general intelligence around 2035, while international cooperation stops warming and a new framework of global collaboration takes shape. In this storyline basic income is fully implemented by 2050 and the Gini coefficient falls to 0.25 or below. AI collaboration systems raise productivity per worker by 40 percent even as the working-age population shrinks. Experts gave it the highest preference score of 4.75 out of 5 but a plausibility of only 2.43, because it runs against current trends in global cooperation and climate action.
