I'm far from the first to highlight it either. The Animatrix highlighted it beautifully what one can expect in a civilization where machines replace human labor in a general sense, and where systems haven't been built to preserve human interests prior to their rollout - tax schemes, job programs, collaboration rather than competition. Ghost in the Shell has had multiple story arcs about the consequences of displacing human labor without care for the consequences of said displacement, because the displacing party gets all the money and power while remaining unaccountable (or so they believe until the very end) for their actions. Cyberpunk dystopias have been intensely focused on it in video games for decades: System Shock, Deus Ex, Horizon, you name it. All of them take those next steps of "what happens when automation displaces a plurality of labor" and reached the same conclusions on strife, despair, poverty, and the general collapse of social order.
These effects have been known for centuries. They are not new concepts.
The folks trotting out "people say this about every technological revolution" are those willfully naive to the past historical harms and ignorant of the plight of others in the present. A flimsy excuse to avoid having to stare into the heart of the system and understand its machinations for yourself, to avoid having to accept that yes, you are a part of it too, and therefore bear some degree of blame for how things function. This isn't the loom, or the radio, or the computer coming onto the scene, but generalized intelligence partnered with generalized robotics to replace the entire sum of human labor. This is what the AI firms openly and repeatedly advertise. This is what CEBros continue to do layoffs for, never considering for a single moment what comes after. Excuses of "people need to find meaning outside of work" or "new jobs will be created anyway" are similarly ignorant in narrative, hollow excuses to avoid the most basic of rational thoughts about the system they're defending beyond whatever nugget of faux-intellectualism they can spout out to sound like they have a clue.
General intelligence, with general robotics, to replace general labor.
There is exactly one way that story ends, and it's not for the benefit of humanity, not under the current systems of governance and systemic incentives we've built for ourselves. It doesn't end with infinite leisure or transhumanism or grandiose visions of utopia, but with the wholesale destruction of human civilization in the name of personal power and wealth.
