On behalf of every junior administrator, overworked IT admin, and security-concerned "cattle" wrangler, thank you.

Having to learn a thousand+ knobs & dials means most will never be touched. I for one welcome automated assistance in this area, even if the results are imperfect.

I think it’s still important to know what those dials and knobs do, otherwise (as the currently top-voted comment says) when things break, you’ll be lost.

That's exactly why it's such a burden.

I continue to be amazed and frustrated that people will simultaneously believe that deeply understanding a programming language is a noble pursuit, but that deeply understanding the software that allows their code to run is somehow burdensome.

Ops remains extremely important and extremely real. You can abstract it away in exchange for higher costs and less control, but ultimately someone at some level has studied these parameters, and decided what is best for your code.
