The bushmen ought to create their own nomadic society and cryptocurrency. Yes, it's a crazy idea, but imagine what they could do.
They could be a roaming clan of assassins or traders - maybe similar to gypsies and have their own international currency trade going on.
That's a deeply cyberpunk notion you just put out there; very appealing fictional vision!
Someone just needs to teach them to use computers.
Heh. While funny, that's not insurmountable. A specialized glyphic/pictorial touchscreen interface with a ruggedized body could be made to work with this setup.
Hmm.
Did you ever see this? Sugata Mitra's "Hole in the Wall" experiment proved just how quickly non-literate individuals (albeit children) can teach themselves to use the actual internet given access. With an interface designed specifically to be ultra-simplified and maximally self-teachable, who knows?
