Yeah and frankly solving world hunger is a vastly more difficult problem than making a Mars rocket. It isn’t really based on intelligence or cleverness in the normal sense. Solving world hunger is more like a long drawn out process of developing countries which cannot really be super accelerated. Transforming countries to prosperous ones without poverty has no quick fixes. It requires time and patience because you are not building a physical device or structure. You are transforming living and breathing people and the networks between them.
