Oh you must be joking. PMs are terrible. And technical people are basically the only ones who actually know how to write things in detailed and unambiguous enough way - it&#x27;s something you can&#x27;t really learn without trying and learning just &quot;how dumb computers are&quot; - which actually means, &quot;how many things people implicitly assume to be self-explanatory or common knowledge&quot;.<p>&gt; <i>I don&#x27;t think the author&#x27;s point is that technical people can&#x27;t write clear instructions, it&#x27;s that technical individuals sometimes mock or deride others over things that &quot;should be obvious&quot;.</i><p>That I can totally believe. But then again, non-technical people like to do that too - often the &quot;obvious&quot; thing being the one that they conveniently forgot to mention at all.
