"Why do I blog this? I find it a very useful approach to design to imagine that I am making the past for some future, rather than the future itself. Artefacts that reflect ideas and inspiration but are things that someday will be quite ordinary, quotidian and unspectacular. Normalizing heroic ideas to the everyday yet exceptionally useful — such that they are impossible to imagine a world without. Like wheels on luggage."
