In my opinion, those 90% of skills were always worth $0, yet we need them to enable the 10% of skills that are worth 1000x. In fact even with AI, you still need the $0 skills to ensure that whatever model you are using is giving you the answer you need. There is a deep connection between our different skills that enable us to create value. Bundling them into separate bins based on how much value they provide individually feels like the wrong approach.
