Plus ça change
Divining the future is scary. Infinite variables coalesce with inconceivable statistics and intimidating predictions to present a seemingly unbridgeable gulf between present and future. On encountering this void, we have chosen to retreat. Back to something familiar, to the one constant in a deluge of abstract information: people. People just don't change all that much. The more the world alters around us, the more the fundamentals at the core of human nature are evident. And if people don't change, then planning doesn't either.
Plus ça change, plus c'est la même chosei
This epigram, written by Jean-Baptiste Alphonse Karr in 1849, is our inspiration: the more things change, the more they stay the same. Whilst the world does indeed keep developing - and as a result the specifics of planning do proliferate - these are really just different iterations of the same core qualities. Although the outward appearance may change, fundamentals are constant.
