Most of modern medicine, by which I mean each discovery and invention in their own right, stand alongside electricity. Particularly vaccines.
AI isn’t there yet. You could turn off AI tomorrow and there’d be a shock but people would quickly switch back. You could not do the same for electricity, medicine, combustion engines (or steam engines/turbines), computers, the internet, modern building materials, etc. You try to swap back off any of those and the modern world (literally and figuratively) collapses. Turn off AI, and there’d be a financial collapse but afterwards everything would return relatively easily to an earlier way of doing things (ye know, the way from just 4 years ago, and which is still 99% of how people do things :) )
I think the Internet is the more apt analogy. But even with electricity, you could have taken it away within the first couple decades of its popularity and society would have shrugged it off. Once they got used to that telegraph thing, not so much.
That's primarily a function of the time for adoption, though, not the utility of the technology. In 20 years, people would not be able to so easily say that they could turn off AI with no impact.
Sure, but compare this to "turn[ing] off" combustion engines a mere four years after commercial adoption rather than 162 years later (now). Back then, going back to horses wouldn't have been as big of a deal as it would be now.
