Speaking of tacit experience, I love watching YouTube videos made by professionals working in industries I’m just a rank amateur in. One thing that occurred to me is that I’ll observe these people casually and repeatedly applying “methods of the art” without a second thought, but then spend the entire episode talking about some specific obscure issue they’re trying to solve. In my mind these have equal difficulty — and in some sense they are equal! It’s just that professionals may have done basics so often they don’t even think about it any more. It’s become a habit, mere tacit knowledge.

I can think of thousands of examples like that: tacit knowledge is the knowledge you gain when you do something many times a day. That doesn’t make it less important, less valuable, or more obvious to beginners.
