My gut instinct is that it will not be an advantage in any kind of knowledge work, because you need ICs to do deep work with enough agency to make the right local decisions. Even if you are very smart, dictating based on an abstract high-level vantage will quickly hit a wall.

That said, I think historically disagreeable types had a bigger advantage because the world was simpler and a lot of times just having the courage of your convictions and appearing strong would be enough to rally people behind you. There's probably quite a bit of latent psychological tendencies in the populace that still allow that to work in some circumstances, but in the modern corporate world, especially tech, you'll get your lunch eaten if you can't get the best out of smart people.
