My concern is more attributed to the tasks that can't or won't be outsourced.

People who maintain a high level of curiosity or a have drive to create things will most assuredly benefit from using AI to outsource work that doesn't support those drives. It has the potential to free up more time for creative endeavors or those that require more deep thinking. Few would argue the benefit there.

Unfortunately, anti-intellectualism is rampant, media literacy is in decline, and a lot of people are content to consume content and not think unless they absolutely have to. Dopamine is a helluva drug.

If LLMs reduce the cognitive effort at work, and the people go home to doom scroll on social media or veg out in front of their streaming media of choice, it seems that we're heading down the path of creating a society of mindless automatons. Idiocracy is cited so often today that I hate to do so myself, but it seems increasingly prescient.

Edit: I also don't think that AI will enable a greater work-life harmony. The pandemic showed that a large number of jobs could effectively be done remotely. However, after the pandemic, there was significant "Return to Office" movement that almost seemed like retribution for believing we could achieve a better balance. Corporations won't pass on the time savings to their employees and enable things like 4-day work weeks. They'll simply expect more productivity from the employees they have.
