Car and motor vehicles in general get you to work and help you do your work. They don't do the work. I guess that's the difference in thinking.
I'm not sure that it's acrually correct: I don't think we'll actually see "AI" actually replace work in general as a concept. Unless it can quite literally do everything and anything, there will always be something that people can do to auction their time and/or health to acquire some token of social value. It might taken generations to settle out who is the farrier who had their industry annihilated and who is the programmer who had it created. But as long as there's scarcity and ambition in the world, there'll be something there, whether it's "good work" or demeaning toil under the bootheel of a fabulously wealthy cadre of AI mill owners. And there will be scarcity as long as there's a speed of light.
Even if I'm wrong and there isn't, that's why it's called the singularity. There's no way to "see" across such an event in order to make predictions. We could equally all be in permanent infinite bliss, be tortured playthings of a mad God, extinct, or transmuted into virtually immortal energy beings or anything in between.
You might as well ask the dinosaurs whether they thought the ultimate result of the meteor would be pumpkin spice latte or an ASML machine for all the sense it makes.
Anyone claiming to be worrying over what happens after a hypothetical singularity is either engaging in intellectual self-gratification, posing or selling something somehow.
