The fields that "AI can't touch" are shit fields that have already been decimated by globalism and immigration. Like cool, farmers, cooks, baristas, plumbers and manual labourers are safe from AI for now. But most paths to a middle class lifestyle are being closed off...
You're right and it's actually even worse than that. If X% of the white collar jobs get replaced by ai that means there are X% more people competing for the "safe" jobs. Over time the "safe" jobs will pay less and less adjusted for inflation because the job displacement is increasing the labor supply making your labor less valuable.
