This is not true for things that matter. It's no coincidence that the example he chooses is movies, of all things.

Skill is the independent variable. When your skill increases, your taste will increase.

It's not more complicated than that.

But a lot of people make it more complicated than that because they have an incentive to.

Because convincing others that you have "taste" is a very useful skill (ha) in our world. It's how you can position yourself as a leader, manager, critic, etc. without taking the time to develop skill yourself. It's a shortcut.

The trick is having to decoupling the two, which this article tries at.

I'd take 1 engineer with skill over 100 with "taste" (whatever that means) any day.

Taste is a thing, but having taste without skill is a myth.
