<div class="sreweekly-description">
<blockquote>
<p>In the midst of industry discussions about productivity and automation, it’s all too easy to overlook the importance of properly reckoning with complexity.</p>
</blockquote>
<p>There&#8217;s a cool bit in there about redistributing complexity rather than simply getting rid of it, using microservices as an example.</p>
