@david_chisnall convergence to mean in multiple dimensions. Take any model and use the domain specific version of ye olde drawing exercise of shading by using your thumb to substitute high frequency detail for shading and bet the bank that those details didn't matter.

What this fails to capture is depriving both participants of the 'jam session'; turning people into unattributed autocompletes makes you forget the person and deprives them of all of the interaction, whether that would've led to collaboration or mentoring.
