Most data annotation comes from educated Western countries atp (the $2 meme is kind of old now since the industry has moved onto RL envs) where the annotators routinely earn multiple times the local median wage.
Edit: And neither our company (a very active, profitable company that sells data to almost all major AI players) nor none of our relevant competition is on this map for some reason. Mercor, Scale, Surge, and Snorkel would be the top players I'd expect to see here. This map has none of them?
It does have Cognizant, which is a international body shop / cheap consultancy that's been around long before LLMs, and mostly builds cheap software fast for existing companies. It also has NextWealth, a company with approximately 1% of the revenue of even the smallest stateside RL Env and labelling players. I'm not sure this map displays literally any meaningful data about the "global labor powering AI"?
