Value exchange necessitates connectivity, but frictionless connectivity thins value. As a design gesture, efficiency leaves out what is unnecessary and focuses on function. Value, though, is the accumulation of utility with aesthetics. So it follows that efficiency and aesthetics are at odds. It becomes of particular importance with creativity-driven value.

If we seek to deliver thoughtful value, the mitigation of friction might act against our interests (thoughtfulness is an aesthetic).

I encourage you to consider where friction exists in your work domains and if you're acting out of inertia trying to mitigate it.
