The point was that new technologies aren't irrelevant because capitalism. Food waste and the shackles of imperialist finance affect different countries disproportionately. But the latter was always cushioned by the fact that, historically, it was straight up impossible for non temperate countries to become food sufficient. At least not in an industrial context. Every advancement in that direction for the past 60 years have created pathways that undermined the basis of imperialist finance.

Yes, if you're American you have an entire temperate continent to exploit. In these conditions it all boils down to redistribution, wether within or outside of capitalist hegemony. But if you've been Indian, Brazilian, Chinese or South African ever since the Green Revolution what you needed was new crops. Productive enough to outcompete cheap exports from the imperial core. That is why countries like Angola became interested in the Brazilian soy, and countries like Indonesia became interested in the Chinese marshy rice. This new rice that the video talks about is revolutionary for pretty much everyone.
