You’re not going to solve the housing crisis with single family homes in suburbs. You need to build dense, walkable cities with good public transportation, and with residential and commercial space mixed together instead of separated. For that, prefab apartments work the best by far, not some giant 3D printer. The USSR and China figured this out ages ago.
On the one hand I agree, on the other, well. Socialist economy, and subsequent transformation to communism requires massive industrial capacity. If a technology can make some part of the process easier or more streamlined, I believe it is our duty to welcome it.
To be clear I’m completely not against 3D printing. It’s a game changer in material science and manufacturing. BUT, it has applications where it works amazingly, but it also has techbros trying to shorhorn it into industries that don’t need it.
