When something no longer has a use how can we use it to create something new and better? How can we repurpose an existing idea/system to make something truly amazing?
Taking ideas out of their original context and applying them to new situations is how we can find novel solutions to problems both new and old.
Taking a system out of context and reinterpreting it through another lense can make for a better overall system and help fix issues with the existing systems.
Decomposing a system, working or not, can show flaws , surface bad assumptions that can be worked through and fixed to make things better.
