I am surprised at the other comments here that state sketching is a skill worth preserving. That's something the author of the article clearly states, hist call to discussion is about technical drawing by hand. And I'm surprised this is still a topic. I studied architecture more than 25 years ago and at that time hand drawing was already phasing out. I have never practiced architecture since then and never thought there would be a debate about drawing by hand again. From what I heard of friends being in the business, doing 2D-drawings isn't a thing in bigger projects anymore, as it is way more economical and less error prone to do the plans with 3D modeling.

Industrial manufacturing still uses 2D. They have to annotate tolerances, materials, and processes just as precisely as the geometry.
