Just speaking from personal experience. The methods that I observed are very modern and very efficient. The parts for the entire building are pre-fabricated and then assembled at the construction site. So the stagnation narrative is more than likely overblown and the folks that think things are slower now should visit some of those Truebeck construction sites and observe for themselves.

I don't think so at all and the evidence points to a profound stagnation in our ability to build. So, if we can't even admit that we're terrible at building fast, there is very little hope. Step No. 1 is admission and introspection:

Have you personally seen those construction sites? Just go and observe, the stagnation narrative is overblown.
