Digital Revolution (1970-present)

The Digital Revolution, from 1970s personal computers to today's AI, has compressed global communication and democratized information at an unprecedented speed. It is transforming human life faster than the Agricultural or Industrial Revolutions (both unranked here), with an estimated 5.3 billion internet users by 2024. This transformation is now enabling artificial intelligence that may ultimately prove more consequential than the printing press (#9 in historical impact). The revolution's pace is accelerating: the smartphone, introduced in 2007, took just 15 years to reach 6.5 billion users—a speed that eclipses any prior technological adoption curve.
