Its a very understandable viewpoint. We believe that you not only can - you should. It may sound a bit utopian today, but look at what these managed cloud services really are: the new hardware. You had to manage every piece of hardware yourself in a mainframe system, because how else? Until you didn't have to. It's just so wasteful to require people do all this semi-manual work. It doesn't make any sense frankly. It has very little to do with the actual products people are building. Sooner or later in such arrangements higher-level concepts emerge and establish themselves. Just like web frameworks most recently, or hardware abstractions (drivers) in operating systems much earlier.

I think you can pay someone to provision infrastructure, then document very well what everything does and hand it over to a human... But completely hand it over to a third party service does not seem convincing to me.
