Do we? I mean, isn't "because they always have" enough of an argument on its own?
I am hardly a libertarian ideologue nor AI-first LLM jockey. But I do think people tend to catastrophize too much. Blacksmiths were killed dead by the industrial revolution. "Secretary" is a forgotten art. It's been decades since an actuary actually calculated a sum on an actual table. And the apocalypse didn't arrive. All those jobs, and more, were backfilled by new stuff that was previously too expensive to contemplate. We're eating at more restaurants. We can find jobs as content creators and twitch streamers.
Life not only goes on after rapid technological change, it improves. That's not to say that every individual is going to appreciate it in the moment or that regulation and safety net work needs to happen at the margins. But, we'll all be fine.
AGImageddon is, at its core, just another economic phenomenon driven by technology. And that's basically always worked to society's benefit over the long term.
