Time will tell. Luckily I'm old enough I won't have to worry. It's an extremely interesting subject though.

Not semantics, with your logic a chain hoist is a machine replacing people.

Have you looked at the dfab website? It's just people using machines for some types of molded walls. Literally in a factory just fabing up small walls with a robot, which still requires a couple people controlling it and it's way slower than a couple of experienced concrete workers just doing it all the selves... Guarantee it's way more expensive too... A few products don't use machines at all and require a team of people to do the entire task. It's extremely far from constructing even a camper trailer, much less an actual house.
