Well. His contribution is somewhat overhyped, at least in South Asian context. Had it not been groundwater, pumps, and electricity, those high yield hybrids would not have been successful. So, it wasnt as much green revolution as it was water pump revolution, and to some extent fertilizer revolution.

I suspect the same with most of such high yield seed varieties. They are often fertilizer and water intensive in reality, if not in labs, which defeats the purpose of having such seeds if you have unpredictable water supply.

It will only feed the planet if they make it available without patents or other intellectual property restrictions. Otherwise it will be just another variety poor people can’t afford.
