AI could concentrate wealth and weaken workers’ bargaining power, sure. I mean, it deserves serious preparation. But predicting an organised 'culling' requires evidence that I don't think anyone on a gaming site would have lol.
If you look at The International Labour Organization, it estimates that one in four workers has some sort of exposure to generative AI, while 3.3% of global employment falls into its highest exposure category. Exposure doesn't mean unemployment though and the report considers job transformation more likely than complete replacement. There is no established deadline for complete automation or defensible percentage chance of an elite extermination program. Reactions to AI all sound so Terminatory lolol. We've seeen too many movies!
Governments are responding, however. Britain targets AI training for ten million workers by 2030; Singapore provides eligible unemployed workers temporary financial support; and the EU regulates AI, including employment applications although these measures I don't think guarantee adequate protection. America’s Medicaid work requirements could warrant criticism I suppose, but that's a whole other issue.
Neither shorter working days nor widespread deprivation follows automatically from technological progress. Ownership, taxation, public services and worker protections (among many other smaller things) influence who benefits. Automating executives would not automatically redistribute ownership, either. We could demand enforceable protections and shared productivity gains, rather than assume either benevolence or extermination.
To scope it down gently lol, our right to live cannot depend on whether employers need our labour.
