I'm not an environmentalist, but even I would prefer we don't graduate to epoxy or resin for home construction. These things are all petroleum based and I have to imagine they outgas for a long period of time after construction. If they do burn, they will also doubtless emit lots of toxic gasses.

I would prefer 3d printing type automation, but applied to compacted dirt or clay. I love adobe and wish it was more popular. Big thick walls that keep out the heat and the cold seem like a no-brainer, if you can reinforce them to not crush you during earthquakes.

Agreed, although we already have a significant amount of petroleum based products in modern (US, anyway) homes: insulation (more and more styrofoam), sealing wraps, glues over fasteners, flooring, and plumbing. Your basic plywood by weight is a large part resins already, although no idea the makeup.

Maybe automation will make more "organic" building materials more affordable or feasible.
