The negativity is no more unwarranted than positivity. Each depends on what problem a person values. In terms of housing the unhoused this doesn’t do anything. In terms of aesthetic possibilities for people with money it provides another option where a wide array of options already exist.

In HN terms, this is a “rewritten in Haskell.” It demonstrates someone understands a bit about 3D printing. It demonstrates some ideological purity. It doesn’t demonstrate a better solution to existing problems.

The complexity of the logistical chain precludes wide spread application where housing is a basic need. You don’t just need the printer machine. You need a fleet of other machines to keep it full of ink. Shovels won’t do.

In the 1950’s, my mentor the late David Crane, FAIA was a young man. He enthusiastically designed precast concrete shelters for post disaster housing. Running the economics at the end of it, its viability was mostly limited to lower Manhattan.

People have been solving housing for millennia. Stick lumber and reinforced concrete are real breakthroughs by virtue of their commoditization.

This is wrapped up in secret sauce. Beautiful as with the myriad other beautiful ways to build.
