Agreed.
I can see 3d concrete printing taking over for floors/slabs as it removes the need for such manual work...and wet concrete is already used anyway, so not much difference. Put DST and a nicely engineered nozzle head on a concrete pumping crane, change the receipe for the mixture a bit...a finishing head to smooth it out while wet....doesn't seem like a massive leap forward to what is currently available???
But for walls? It will have a market, but I doubt it will be more common than bricks/blocks are.
