You’re probably out of luck trying to convince this person of your opinion. However if it comes up again and you want this person to walk away, I’d recommend mentioning the horrible working conditions that content moderators have to go through. Contrarians don’t like unassailable facts.
Content moderators are superexploited. These employees primarily work from African countries like Kenya, so there’s a whole second layer of neo-imperialism that I won’t get into right now. They’re given poverty wages, sometimes as low as $1.30/hr. Because they’re content moderators, they have to look at images and read descriptions of traumatic events without respect for mental health. OpenAI, Amazon, and Facebook have engaged in aggressive union busting tactics for these workers as well, though workers were still successful in organizing one of the largest labor unions in Africa.
