It is slower than events and faster than structures. For Braudel, conjunctures were the middle register where most of the quantifiable movement of history actually happens: price cycles, wage patterns, migration waves, technology diffusion. Applied to AI, the conjuncture is where professional displacement, institutional adaptation, and organizational restructuring play out — and where the software death cross lives as a phenomenon.

The concept predates Braudel; François Simiand and the price historians of the early twentieth century used conjoncture to describe economic cycles. Braudel's contribution was to generalize it: not just economic cycles but social, demographic, technological, and institutional cycles all operate at this medium-term scale. The 1949 Mediterranean tracked Spanish price cycles alongside Ottoman population movements and Mediterranean shipping patterns, demonstrating that conjunctures in different
