Game development is a very specific use case, and NOT what most people think of when talking about devs vs ops.

I'm talking enterprise software and SaaS companies, which would be a MUCH larger part of the tech industry then games.

There are a large number of devs who think public cloud as infrastructure is ALWAYS the right choice for cost and availability for example... Which in my experience is actually backwards, because legacy software and bad developers fail to understand the limitations of this platforms, that it's untrustworthy by design, and outages insue.

In these scenarios understanding how the code interacts with actual hardware (network, server and storage or their IaaS counterparts) is like black magic to most devs... They don't get why their designs are going to fall over and sink into the swamp because of their nievete. It works fine on their laptop, but when you deploy to prod and let customer traffic in it becomes a smoking hole.
