Awesome. We need robots to cut the cost of construction.

The cost of the land is: [cost of the house] - [cost of construction].
I guess the cost of construction doesn't matter much. The main cost of builders is probably to buy the land, and if they were to cut construction costs, land prices would just go up correspondingly to lead to the same final prices.

Nobody will believe it until the robots fart loudly, curse, drink beer and chew tobacco while working.

This is bricklaying, not building a house. Most houses in the US are not built of bricks. Building a house using standard wood boards or engineered boards is much cheaper than building a brick house. For large apartment buildings, steel framing is much less expensive and safer than a giant brick building.

Plumbing, electrical work and internal finishing are also more expensive than framing.

The brick laying approach might be useful for building a brick wall/fence around the yard where those are allowed by zoning code.

BTW, the original Levitt-town took 1.5 days to build a house, on average. That was circa 1950. Much less code requirement back then. In fact, most towns and cities started to have zoning code in the 1960's, precisely to prevent the Levitt-town approach result in too many houses in their town/city.

Yeah but what about the rebar and pouring concrete to fill the CB Voids?

That wall would not be very sturdy without it. There was no pressure placed on those blocks to help compact it so water is forced out. This allowed less air pockets when the mortar dries, and increased strength. You video wouldn't play I had to see a video on YouTube.

Didn't need them, people generally over built things back then. Modern materials are so cheap and flimsy we need more building codes than ever.

My house was built in 1952. I took a sledge hammer to liberate one room of the main original house to the 1970's added MIL quarters addition.
When I slammed it with the 15lb sledge hammer, it bounced back and almost hit my head. Didn't put a dent in the wall. I got a Saws all and found...

Dade County Pine(termite, rot proof/Now extinct)
Had a gypcrete board with large holes nailed to that, an inch of Mud slathered over that, a layer of metal mesh pressed into that, a layer of plaster over that.
If any force of nature were to ever lift my house and toss it in the air. The walls would all go as one solid piece. It would not implode into a million pieces.

It's either an adequate vehicle for speculation and debt slavery, or it's a bust.

A lot is also permits and other taxes/fees. Not just the land.
