We're dealing with two separate things. The mass timber that would be used in tall wood buildings, for example, is not a particularly technological product. It's taking two-by-fours and laying them this way, putting some glue on them, then taking two-by-fours and pressing it all together. It ends up with a material that can substitute for concrete very effectively, but not very technological. It requires some expensive machinery, but the process itself is quite simple.
