I love it, you dismiss long established, well researched logical conclusions based on understanding of software development and backed by studies…in favor of your anecdote about an engineer you failed to manage properly.
In my experience people who make extraordinary claims about how bad the “guru” employee is are just ignoring his actual contributions because he is focused on getting things done rather than shouting “yes sir” to their arbitrary and clueless demands.
Worse they think this anecdote justifies destroying the productivity of the entire company.
And yet here you are repeating this exact cliche.
It is still not logical.
