Most of those "houses" are glorified emergency shelters.

Ignoring the fact that concrete is one of the worst materials you can build with in terms of environmental impact, 3D printing doesn't solve the problem of building systems...

Electrical, plumbing, and sometimes even HVAC assemblies are typically housed in wall cavities. Building your walls out of a solid, homogeneous material leaves no space for these critical building systems, and even if they did, they would be impossible to maintain once the walls are closed up.

Additive manufacturing has its place in the AEC industry, but anyone claiming 3D printers will essentially replace traditional construction is selling you a lie.

No, it can't. Unless you are taking about very specific ground floor only projects. Modern construction materials like AAC are insanely fast, whole walls for a single floor can be done within 2 days, 3rd for preparing the reinforcement for ceiling, 4th day you are done...

Also - walls and ceiling in my house is less than 12% of 'developer' state, meaning all construction and installations done before finishing work can start (floors, furniture, lights and so on). Walls are cheap.

No it cannot quit posting this bs. Someday machines might do it better but “3D printing” ain’t it . At best it does the cheapest easiest part of home construction, the walls. Homes are expensive because they are now incredibly complicated and need to last for 100+‘years.

Shit, about twenty years ago people used to leave old computers out on the street. I'd pick them up and swap out faulty components with working bits from other machines I'd found. Eventually set up a free internet cafe thingie in a local kind of community squat. Only had half a dozen machines working at any time and there was constant maintenance but it was an inner city area where everyone except the drug dealers was broke and it was somewhere people could get online for free. It's been years since I've seen old computers dumped like that. People seem to hang onto them as long as they can, which is great - too much e-waste anyway. Plus everyone has tablets now I guess.

I remember like 10 years ago I kept seeing all these stories about how the PC and laptops in particular were dead and tablets were the future since they were outselling them. Not that, like, tablets were new and people were buying one for the first time.
I love my tablet, but for me it's really more of a toy. Scrolling through something sitting on the sofa or watching a movie on a plane. It's not something I replace until my old one won't function anymore and even then if I found myself in a tough financial situation, like, say the current state of inflation, it's not something I NEED.
