The system is unfortunately exclusionary of some parts of the world due to extreme conditions at those places - which are much worse than a single war. It's more like decades of never ending wars and extreme droughts. Africa's problem isn't that they don't know how to code and as a result make less money and can't afford food, the troubles there are much much bigger and as a result they are outside of the supply chain we have.

And yes, by global event that scares me is exactly the climate change.
