Crucially, this shows the difference between Traditionalism and just having a lot of cultural context. Culture itself is just weight - more of it is harder to change, but it's the same difficulty no matter how fast you go. Traditionalists, on the other hand, will fight you harder the more quickly you're changing cultural facts.
their general-purpose nature means that our minds take on the additional complexity of context switching as we use our tools for multiple simultaneous tasks, and indeed this generality means that they can be quickly adapted to new contexts. contrast this to specialist tools which, once learned, provide significant increases in efficiency in the specific context to which they have been adapted (including the benefits of increased concentration owing to lack of distraction!) but cannot always be re-engineered easily to suit new contexts.
