> The system uses a construction adhesive that's stronger than mortar and dry within 45 minute Notably absent from this demo. And probably a harder problem than just placing bricks down.

  Why don't bricklayers use this magical substance? If there's nothing to even out the courses, then unless your bricks have absolutely perfect dimensions, it's going to go all wonky quite quickly.

    Building glue is not magical and it's widely used, at least in western Europe. Glue is rapidly replacing mortar (just not for foundation and facade stone). Also, it dries a lot quicker than 45 minutes. A builder doesn't have to wait at all to add additional layers. And at the end of the workday, you just drop you glue gun, no need for lengthy cleanup of everything used to make mortar.

    my house was built like this. The bricks had perfect enough dimensions for the small bit of glue to compensate Only for indoor bricks, wienerberger Porotherm https://www.wienerberger.co.uk/tips-and-advice/blockwork/how-do-you-lay-clay-blocks.html https://www.wienerberger.co.uk/tips-and-advice/blockwork/how...

Glue is getting popular for ytong and similar already.

  If the "glue" you're referring to is what I think I've seen, it's still much thicker and filling than what you can see in the video below (where you can still see light through the gaps)

Actually, the unreasonably long boom arm is bouncing around significantly, yet the bricks are being place precisely independent of the boom movement. There's some nontrivial PID going on in that brick placement. Plus planning where to place the brick. Optical, lidar? This is impressive imo.
