California almond productionPay phones remaining in the US
California almonds going up. American pay phones going down. The negative correlation is so neat it feels staged, as if the orchards were quietly absorbing each retired booth and pressing it into a tonnage report.
California almond output more than doubled between 2005 and 2022 as growers replanted higher-density orchards across the Central Valley, riding the global plant-milk and snack-nut boom. Pay phones did the opposite: from roughly two million in service in 2000 to fewer than 100,000 today, retired by mobile coverage and the Bell-system breakup. Both are technology stories on different farms — one agricultural, one telephonic — and they share a window because the same span of years (2005 to 2022) was busy modernising one infrastructure and quietly dismantling another.
Progress arrives lopsided. Some industries triple while their neighbours go to scrap. The years are blunt accountants.
