The 'backlash' seems to be from the fact that people, esp white collar workers are finally realizing what blue collar folks have been feeling for quite some time. That an overwhelming majority of the technology driven productivity gains accrue to capital owners, not workers and AI is the ultimate productivity tool.
It doesn't help that capital owners no longer feel it necessary to even pretend. Like when CEOs openly salivate at the prospect of firing all workers and replacing them with AI. When people see their electricity rates go up to subsidize billionaires building AI data centers. When they see their real wages falling continually while they are told how good the economy is.
If the gains from AI were shared even a little with the regular people, they might not have the deep sense of unease and sometimes open hostility that we are seeing now.
