Oh wow ---> Oh shit
Fine example of what happens when you do ABSOLUTELY EVERYTHING POSSIBLE to eliminate human skill and human scale. The brand-new 47-story Leadenhall building in London is experiencing its first sort of slightly vaguely coolish weather, and it's starting to fall apart. Compared to most places in the world, London doesn't have temperatures, though it does have wind. Today the low reached a bone-chilling (for London) 44 F, and the building is starting to drop arm-sized "megabolts" through its interior and (somehow) out to its exterior.
According to this, the Leadenhall was designed by computer and pre-assembled offsite in huge modules, which were then hoisted and fastened in place with a few giant "megabolts".
With very few wet trades on site, construction is very much an assembly process, with an on-site team of only 150-200 compared to the 500-600 normally required for a building of this scale.
Well, that's nice that you avoided employing "wet trades" (ie real craftsmen). Now you'll be able to employ thousands of unskilled illegal immigrants in the cleanup and rescue teams, and thousands extra in London hospitals and morgues.
Looking on the bright side: The building is completely unnecessary, and it houses nothing but Satanic predators and Satanic parasites. All "dry trades". So its fall will not destroy any "wet" humans, unless some non-Satans are unfortunately walking through the parasite zone at the time.
