From what I'm understanding the hard part of doing that stuff concrete is curation time. There's a lot of projects trying the "easy" route and effectively do additive 3D printing with concrete instead of glue. Conversely, they have the same problems... they look pretty ugly: https://www.realestate.com.au/blog/wp-content/uploads/2016/0...
Doing it "properly" means building proper moulding, rebar, vibration casting all the stuff that sounds like almost impossible to automate with 2021 technology.
Bricks have the advantage that they're pre-cured, so you don't have to wait ages until the wall actually supports something — and if that something is just the next layer.
So what people do is you build the "ugly" way (usually large panels, maybe even prefab, I doubt 3d printing is working that well right now), then cut bricks into 5 slices and stick those slices on top with glue. You can't tell it's not a brick wall except when you're standing right against it.
And of course, you only do this on visible walls. It can even be done on top of wood.
Paint or stucco would be a big improvement to the aesthetics of the primary exterior surfaces that house … and changing the hideous orange puke trim color.
