Couldn't you argue that the majority of cars are built mostly with robots? There may not be a brake changing robot, but I bet there's a brake installing one. When it gets to the point that the automated labor is cheaper than or more efficient to the human labor, you'd see the switch.

Amazon is testing/using automated warehouse robots to stock their shelves- I imagine it would be a while until we did grocery stores with robots as it is a much less controlled environment and human beings are unpredictable. Plus running over a kid with a robot would be bad for all parties for a very long time.

This is the nature of technological progress. The loom, the cotton gin, the automobile. They were thought exercises, then flights of fancy, then the differentiator between visionary adopters in the market, and then sometime later- the absolute bare minimum for being able to stay in the market.

AI everything/everywhere isn't that realistic- not because of feasibility necessarily, but because of the perceived value or lack their of for any given application. But as a means to replace rote, occasionally hazardous and/or arduous tasks, I feel like that would be a great place to start. No workman's comp when someone falls off a ladder or makes a mistake. No father or mother that dies on the job when an improperly placed load shifts and collapses on someone. 24/7 shifts that don't involve working people to death or mental failure.

We're probably a few decades out at least, but we'll get there. Hopefully gracefully enough to figure out what to do with a swathe of society that's been made redundant.
