You&amp;#x27;ve commented throughout this post about how this is boring and the Pinterest team is incompetent.  Why?&lt;p&gt;I found it quite interesting.  I&amp;#x27;ve been working in deployments for over 20 years at some pretty big places, and never really though about this before.  I now have a new tool in my toolbox, and I&amp;#x27;m quite happy about it.</text></comment>

Maybe you’ve only worked at large companies who have had time to optimize things for years (and even then, I see grotesque software decisions at my large company quite often). Try accepting that software is often written poorly optimized on the first pass, for good reason, and learn to celebrate the wins without needing to shame someone.</text></comment>
