My counterargument: The real work is not increasing complexity, but boiling down complex concepts into ones that can be worked with and exchanged easily. This is why math is so vital, and why tools that 'hide' layers of abstraction so powerful.

A physical metaphor: Shipping containers don't make things harder to ship, even though untold millions of containers contain a lot of heavy things inside of them. It's not about the box full of stuff, it's the entire vastly more efficient global shipping industry! This is, I assume, why Docker uses the container metaphor.
