It's interesting to see the different forays into building process automation. I've come across a couple other brick-laying solutions, and a few 3D-printing-inspired ones (using concrete as the extruded medium). I do think the approach that is most likely to succeed would be pre-fab components assembled on-site. Some of the immediate challenges that the demo videos didn't show include the placement of headers / spanning gaps, and keeping the courses even / level. It's interesting they introduce some custom adhesive; I'm guessing because mortar delivery in that setup was prohibitively expensive. Interesting choice with the flat cinderblocks -- one would think for a method like this, they'd choose some type of an interlocking block, to make alignment easier and increase contact surface for the adhesive. I'd compromise on the saw in that case -- lose the dimensional granularity (eg have the wall dimensions be specified in 6" increments) but get rid of a complex component in the pipeline. These folks must have a solid business plan to have gotten this far - I guess the value proposition is lower cost than traditional building methods, coupled with 24/7 builds?
