I'm thinking of jobs that require a wide skill set, adaptability and a lot of moving around. Like regular construction work. I can't imagine automating the construction of large structures without using robots so advanced they can do anything a human can, then you'd have post-labor economy and robots writing your welfare checks for certain by then.
I can easily imagine that, heck we can even put together a program to design the structure given the parameters you want. At the end of the day building a structure is really not all that complex, it's a just a series of predictable jobs, which is what robots excel at.
Machines can easily be made to be adaptable by giving them the ability to swap out parts, they just can't easily be adapted to do things outside of what they were intended to do.
Construction requires a bit of mobility I don't see a big dumb clunky robot being good at. Designing buildings, possibly. Actually just climbing up a ladder and putting in panes of glass? I don't know how a robot could do a better job then a person could.
Well now that I think about it, though, buildings will be prefabricated into modules or sections, put on trucks and bolted together at the building site and I can see robots doing that. They'd just change the way buildings are constructed to make it fit the strengths of an automated workforce, instead of the otherway around. It's kinda dumb to drag a bunch of raw materials and assemble them by hand at a build site anyways. Imagine if that's how they built cars, they came by with a truck full of car parts and a bunch of day laborers assembled it in your drive way over the course of a week or two.
With 3-d printers I guess you could apparently have a big printer in your garage and you'd just print your car off from a blueprint off the wiki and drive off.
Except there is no guarantee the robots will care about us at all. Hell, they might even become outright hostile once they have enough autonomy. Why tolerate these primitive meatbags when they keep getting in the way?
Call me a nutjob all you want, but they are programmed by beings that do the exact same thing.
I know it's a sci-fi trope, but there's no point in programming emotions like malice or resentment in machines, or even self-preservation. Just make lawyer-bots that will sue anybody that damages other robots. Show robots that litigation is the civilized alternative to violence.
If we can automate every step of the production process, from raw material to finished product, is there any reason not to give the final product away for free? (Assuming its nothing dangerous)
The labor might be endless, but raw materials and energy are still finite, so there would have to be some way to distribute/ ration it.
