Bill Gates predicts AI will bring an optimistic future after a 20-year adjustment period. He divides AI development into two stages: current turbulence and a future age of abundance. During the transition, AI may disrupt jobs and empower criminals, requiring mandatory safety barriers to prevent catastrophic misuse. Once stabilized, AI and humanoid robots could solve resource shortages, creating an age of abundance. Gates emphasizes that navigating this turbulent phase with minimal loss is critical, urging lawmakers to establish strict monitoring mechanisms despite potential industry costs.
