I think more and more industries have these insane levels of concentration.&lt;p&gt;In 2016, an explosion at a single industrial gas facility caused a whipped cream shortage in the US. [1] I mean in the scheme of world problems, that&amp;#x27;s one we&amp;#x27;ll survive, but it does illustrate how vulnerable a lot of our supply chains are.&lt;p&gt;In 2007, the shutdown of the Canadian Chalk River reactor caused worldwide shortages of isotopes used for medical imaging, with real life consequences for patients. [2]&lt;p&gt;There are probably countless other examples. In the end, its the direct consequence of the constant quest to lower production costs and increase efficiencies.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.theatlantic.com&amp;#x2F;science&amp;#x2F;archive&amp;#x2F;2016&amp;#x2F;12&amp;#x2F;the-deadly-explosion-behind-americas-whipped-cream-shortage&amp;#x2F;511118&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.theatlantic.com&amp;#x2F;science&amp;#x2F;archive&amp;#x2F;2016&amp;#x2F;12&amp;#x2F;the-dead...&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.nytimes.com&amp;#x2F;2007&amp;#x2F;12&amp;#x2F;06&amp;#x2F;business&amp;#x2F;worldbusiness&amp;#x2F;06reactor.html&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.nytimes.com&amp;#x2F;2007&amp;#x2F;12&amp;#x2F;06&amp;#x2F;business&amp;#x2F;worldbusiness&amp;#x2F;06...&lt;/a&gt;</text><parent_chain><item><author>maxander</author><text>Every once in awhile, one hears about some accident like this one at a single, physical factory, followed by a laundry list of tech companies that are adversely effected.

If you can afford it, and it’s technically possible (no special deals or tech), you’ll require at least some functionality at a second fab. What you cannot do is immediately get a second fab up and running. There’s a surprising amount of process tuning, sometimes accommodating new device models, and design rule differences (they will not guarantee or sometimes even start if they’re not meet). It’s in no way turn-key if you’re anywhere near the limits of what the fab can do.</text><parent_chain><item><author>maxander</author><text>Every once in awhile, one hears about some accident like this one at a single, physical factory, followed by a laundry list of tech companies that are adversely effected.
