Unrelated apart from the words "rock" and "construction": I wouldn't be surprised if we see dry stone construction becoming very practical thanks to advances in computer vision and robotics.
Dry stone construction is incredibly durable -- it doesn't rely on mortar which can weather away -- but it is limited by needing to reshape stones to fit together tightly (often by making flat surfaces). A human stonesmith can look at a handful of stones and find one which is close to fitting in the necessary spot; but a computerized system could scan thousands of stones and build tightly-fitting stonework with minimal need for reshaping.
An interesting thought, im pretty wary on most automated construction techniques, but dry stone construction does seem like a good fit for automation. It needs to be done before any other construction is really done and takes a decent chunk of time even for a team of humans so not a lot of people or other things going on around the area or in the way. There are still some issues that need experimentation. You can go 99% of the way with fairly simple imaging, but that last 1% can be tricky and usually requires tactile sensation and probing and pushing on stones to get a rock solid fit, but perhaps the actual technique/style of stone fitting would alleviate that last bit.
