How will Golden Rice be used in the future?

Could you elaborate on the potential applications of Golden Rice in the future? I'm particularly interested in understanding how it might contribute to global food security and nutrition enhancement. Will it be widely cultivated in various regions? How do you see it addressing nutritional deficiencies in developing countries? Moreover, could you discuss any potential challenges or barriers to its widespread adoption? And, in the longer term, what are the prospects for Golden Rice in terms of its impact on agriculture and society?
