Oh thank you for sharing! I had tried describing this earlier in my career and had call it "The complexity shell game" as in attempts to hide complexity only serve to move it around and to trick yourself it's gone. I would much rather use an existing standardized term, so I'm switching to Waterbed Theory, thank you!
I call it the conservation of effort. If you are able to save mental energy in one place, it necessarily has been spent in another.
Its amazing how humans come up with the same things independently.
