Just to clear up the misinformation:
Musk, tired of the shit, said he would literally spend $6B (his entire wealth at the time) on world hunger if the UN explicitly stated how $6B could solve world hunger. When the UN said "lol actually it can't", then Musk did nothing.

The US government literally spends $6.27 trillion a year. $6B is less than 0.1% of that. If you honestly think that can make a significant difference in world hunger, than harass your damn government to consider allocating that small amount for that noble cause, instead of allocating it to the fucking military or something.

There's a zillion reasons to shit on Musk if you want, figure out better ones <.<.

6 billion dollars won't end World Hunger, teaching the third world how to grow and cultivate crops will.
And maybe ending the Chinese Communist Party too.
