Ok...
What such questions tend to lack in their fanciful speculation is perspective (context). So I'll take a few steps back and try to provide some.
Part 1: What Do Humans Want from Technology?
Fundamentally, what separates humans from animals is our nearly unlimited ability to use tools, thanks to our big brains and opposable thumbs. The entire history of human development is based on using tools to reduce our workload and increase productivity -- as well as accomplish tasks we are not capable of doing naked.

The qualitative improvements may be hard to quantify (by definition), but the quantitative ones are not:
I could probably travel 30 miles in a day, with a small pack, on foot. On a horse, maybe 100 miles, with a larger pack (never tried either of those things, so I don't know - I'm just making it up). Later this month, I'll be driving 450 miles in about 9 hours including stops, carrying probaby only a couple hundred pounds of gear but could do thousands if I wanted. An orderds of magnitude improvement. Even planning the trip; no more spending an half an hour with a map, planning and measuring the route and then hand-calculating the time; google maps does it faster than I can type in the request.
We build buildings 100 floors high with cranes capable of lifting dozens of tons. If I want a bathroom floormat, I don't weave one myself in 3 days, I drive to Kohls where one that came off a machine in China at a rate of 10 per minute is sitting there waiting for me.
If I want to communicate with my sister in Boston I don't write a letter and then hire a Pony Express rider to run it up there in a few days, I just Skype her.
The point is, all of our tools make us better and faster at things we want to do and enable things we otherwise wouldn't even be capable of without them. And that progress - while uneven - has produced exponential improvement.
But what hasn't change much at all is the human's workload. Over the past century, most people have worked between 35 and 60 hours a week, always.
Why?
Because despite some people's protestations to the contrary - they are fooling themselves - we all want "stuff", because "stuff" is just awesome. I could choose to work fewer hours at an easier job, but then I wouldn't be able to afford air conditioning, Netflix, a good car, a telescope permanently mounted on my deck, etc. Any one of those "things" I own would make a medeval king drool, and the combination of them is just fantastic.
The point of all of this is that automation reduces our workload allowing us to do more, better. The net result is a near constant workload for humans, for a long time in the past, which will almost certainly continue for a long time in the future.
But what about robots/AI? Can't they make human labor obsolete?
