Barely adequate, or even incompetent, is perfectly fine as long as they can make money. I’m not even sure a major AI fuckup would stop the adoption of these technologies, especially because they show no sign of slowing down development. Mechanical Turks have limitations. Sure, now they are cheaper, but as soon as a barely functional (but still functional) “AI” comes along that is cheaper to use, you can wave goodbye to the digital sweatshops.
