We do this. Have you ever heard of UN World Food Programme? $14B funding in 2022 (since then dropped drastically, guess why).
Has it solved famine? No. Would it solve famine if it got the funding it needs? Unlikely.
Because you cannot just spend billions of dollars to send amazin food parcels across the world and expect that to fix climate change, draught, poverty, colonialism, racism, illiteracy, lack of education, and propably 100 other issues all contributing to the fact that we still have not end hunger. And no, AI won’t solve it either.
