Probably not the point you were making but OpenAI is paying (a small group of) people pretty high hourly rates (like 70-100$/hr) through their “redteam” program
This is vastly different from other, non-AI companies hiring people to prompt AIs for them. And a quick google shows that it's not a full-time job at all.
This sounds more like QA testing. Preventing situations that could hurt the public image of the company, or similar.
