&gt; There is also no reason why Bob can&#x27;t adapt his communication to whoever is saying &quot;your foo implementation sucks&quot;.<p>Except that it&#x27;s a lot easier to not say &quot;your work sucks&quot; than it is to not feel upset when someone does. And most people will indeed adapt over time, so it&#x27;s a pretty silly reason not to hire someone.<p>&gt;I find it to be an exercise which saps my mental energy and distracts me from increasing shareholder value.<p>The thing is, I don&#x27;t feel like I need to actively think about people&#x27;s feelings to not say &quot;this sucks&quot;. I just do it naturally in response to different social contexts.
