Automation: yes, but...
I do not fully agree with automatic patching. You never know the side effects of applying a patch. My approach is that you should first deploy on a few workstations or on a test server for critical applications, then test, then deploy full-scale. Otherwise the impact on availability of systems can be dramatic.

One of the issues faced by infra is that some patches are often marked as missing, although a newer one is superseding. This creates headaches.

And risk-based approach is also key. Do you need to patch everything? 

Some systems do not need to be patched every month, like MS servers. You can check for new patches every quarter or every six months. Is there a need for automation then?

Scanning not only option
It is important to add that, it is not needed to scan to detect a vulnerability. Too many orgs rely on scanning as the primary method. Use scanning to know your asset, match up against a Vulnerability Intelligence Feed, and then drive your VM based on risk. You don't need to patch all vulns at once, but you do need to know about all the vulns that impact your asset so you can make a risk based decision.
