The replacement will not be laying bricks but new technologies. Computers didn't replace human "calculators" by using abacus.

as a counterexample your clothes are stitched with thread, even when automated. Sure the stitching is different but it's still a style that's appreciated.

like thread, maybe bricks have a place still.

Maybe stuff more like this[1]? 1: https://www.youtube.com/watch?v=GUdnrtnjT5Q

But a 'robot' built that house... Didn't you say prefab would put robots out of business?

Prefab robots with delivery infrastructure put local robots out of business.

Bricklayers are already a dying breed... workers compensation makes it way too difficult to build many structures out of brick. Most "brick" or "stone" you see in new construction is some prefab panel glued to something. IMO you'd employ more bricklayers doing trim work and operating the robot than you do now. And we should move away from shitty manufactured wood, glue and toxic treatments.

Prefix that with "In the States".

Whats the setup time for a robot that lays bricks? If you've ever seen a team of skilled masons/bricklayers build a wall, they're pretty freaking fast at it. I imagine the time to transport/setup/calibrate/etc a robot would eat up whatever performance gains it would have over humans - unless perhaps its a really big job, but how many of those are being built these days?

Bricks are expensive these days, and laying them is an artisan art and skill.

Where I live in California houses are currently erected in days out of cheap wood and cladding. As soon as it is feasible this process will be automated and ways found to construct them more quickly using the cheapest materials.

We recently had some terrible fires where entire subdivisions burnt. Dozens of houses burnt simultaneously yet the trees and cars didn't catch fire. This was due to embers landing on roofs and getting into attics - the houses went up like paper bags.

Making sure the next generation of cheap building materials are fire retardant and robust is a worry given the rush for maximum profit for minimum investment and wealth sharing automation brings.

Why emulate a human at all? I think that's the main issue. There has to be a better way to lay brick once you get robots involved.

It's probably anticipating corners and arches, but for the majority of bricks this seems quite inefficient. Bricks could be rolling off a conveyor belt in to place.

Conveyor belt doesn't help, as you would still need an arm to take bricks from the pallet and place them on conveyor.

Why aren't they using shims and jigs? If you want to line it up right, make sure you have the right amount of mortar in the right place, etc, put a jig around it with some shims. It's the easiest way to build anything precisely that has to be done over and over again.

If you have the wrong amount, consistency or distribution of mortar, the jig won't fix it.

That might be the easiest way for a novice to do it, but would it be the fastest for someone who has experience?

Fairly significant, apparently - you have to put up a scaffold alongside the wall for SAM to work. (And presumably, you need firm, open ground to put the thing on.) And they can't do corners or complex features, so when you hit those you need to either stop the machine or move it to a different part of the project. Headlines say they're 6x faster than normal masons, but that's during a given span of operation; over the course of a day, with overhead, it's apparently more like 3x.

That said, the machines are in field use, since masons are scarce and expensive. You're right about the big jobs, too; they're apparently pretty much limited to sites like universities and hospitals which have lots of big, featureless walls. The Tech Review article about it is much more informative than the NYT one here. [1]

I think this sort of automation worry seriously over-generalizes from factory robots. Robots are spectacular at doing repetitive tasks with nicely-arranged inputs and fixed workspaces. Hence, Amazon warehouses and Ford factory floors. But (as the SAM people admit) outdoor, new-worksite tasks are going to involve way more mixed human/robot tasks.
