The compute used to train notable AI models has doubled about every 5.7 months since 2010, against roughly every 20 months in the decades before. Researchers count that compute in FLOP (floating point operations), the total number of arithmetic operations performed during training. This article uses an open dataset of 457 notable models published from 2010 to 2025 to show how fast it has grown.
Large numbers are hard to feel, so here is one way to scale them. If all 8 billion people on Earth each carried out one calculation per second, without stopping, they would manage about 2.5...

Europe is growing older, and the number of people of working age is about to fall faster than it has in decades. Using the United Nations' latest population projections for 36 European countries, we looked at how many people will be aged 20 to 64 in 2050 compared with today, and how much migration changes the picture.
Fertility is the main driver. The median fertility rate across these countries in 2025 is 1.46 children per woman, and 24 of the 36 are below 1.5. The highest is 1.74.

Prices rise almost everywhere, but the speed varies enormously. Using the World Bank's consumer price index, we compared what a basket of goods cost in 2000 with what it cost in 2024 across 158 economies. In Japan it cost 11% more. In Angola it cost 355 times as much.
A saver in Sub-Saharan Africa faced about one and a half times the yearly erosion of one in Europe and Central Asia. Holding cash for two decades was a steady drag in Germany and close to a wipe-out in Angola or Iran.
