Your comment seems to miss that the author is speaking about technical drawings, not sketches, in particular this part:

> And I would argue also that this scarcity of ability was already a problem for the last 100 years. The whole iterative process of ideation (ie. designing, sketching) gets so much less intuitive, if one has to pull out a ruler first, or boot up his machine.

You mention sketching explicitly, which is exlcuded by the author. And making technical drawings without a ruler seems insane to me.

> In dev-speak, removing hand-drawing from the skill set of architects entirely is as if you were deliberately removing HMR from your local web dev-setup.

That would be true if you removed sketching, but removing hand-drawn technical drawings is more like replacing hand-crafted optimized assembler code with an optimizing compiler.
