If you're free to define "all talk" as "not useful" then yeah - you've created a tautology. All I'm saying is some folks that are awful to work with side by side as technologists are super useful to an org in other places.
One person's 'all talk' is another person's 'all walk'.
Do recall that the reference for "all talk" in this conversation was
> never wanted to take on advice, always fought on really shady grounds, but he fought everything, almost like it was either his idea of what was on-point or nothing
Yes, you can be productive through communication, but if that's the kind of "talk" you want in your C-suite then I don't want to work in any company where you have influence.
It's almost like communicating effectively requires detailed knowledge of the real world, knowledge most often and most effectively gained by... doing things.
One person's 'all talk' is another person's 'all walk'.
