For the last several decades, one avenue of technological progress has towered over nearly everything else: semiconductors.
There seems to be a few factors at work. One is the fact that a brick or block isn’t simply set down on a solid surface, but is set on top of a thin layer of mortar, which is a mixture of water, sand, and cementitious material. Mortar has sort of complex physical properties - it’s a non-newtonian fluid, and it’s viscosity increases when it’s moved or shaken. This makes it difficult to apply in a purely mechanical, deterministic way (and also probably makes it difficult for masons to explain what they’re doing - watching them place it you can see lots of complex little motions, and the mortar behaving in sort of strange not-quite-liquid but not-quite-solid ways). And since mortar is a jobsite-mixed material, there will be variation in it’s properties from batch to batch. Masonry machines have constantly struggled with the mortar aspect of masonry; many of them simply ignored the aspect of the problem. The academic studies of the late 80s and early 90s were often based on using mortarless walls, wall systems that don’t require mortar joints (such as surface bonded masonry), or mortar alternatives that behaved a little more predictably (which is what Hadrian ended up using). In his 1996 paper, Pritschow comes right out and says that trying to solve the problem of handling mortar is too difficult. The folks that have figured out how to reliably apply mortar still can’t quite manage to produce a clean mortar joint - they simply slather the mortar on there, requiring workers to follow behind and clean it up. In some ways efforts like SAM don’t look all that different from the 50-year-old Motor Mason in this regard.
