Some network automation skeptics came to that place the hard way: they got burned by half-baked semi-tested systems. This is what one of my good friends had to say in a LinkedIn comment:
I am suspicious of automation, as I’ve unfortunately seen too many outages caused by either human error or faulty automation. Every time it required human CLI/GUI intervention to correct it. The problem is that the more automation we push, the fewer people know how to use the “old school” way to administer stuff.
Network automation is not the only IT discipline that could cause hard-to-correct errors requiring manual intervention. I’m positive everyone knows at least one horror story resulting in manual tweaking of the Windows registry, or a sequence of arcane SQL commands1.
