The biggest difference is most of the automations of the past just shifted the working from doing the hard work to using the automation to do the hard work, a mostly neutral transition. Now significant portions of automation completely replace the worker, needing no human behind the wheel, but instead maintenance, which is multiple robots and thus multiple jobs per human, and builders/developers, which for the most part are one and done per job, thus not creating a sustainable job source.

This is not a bad thing, but the fundamental "work to live" needs to change, as so much of what needs to be done for society to function will shift to robotics and automation with very little oversight.
