I'm specifically arguing that there has been little meaningful innovation between the late 1960s and 2020s. Outside internet protocols, applications, and appliances, what's been invented since the late 1960s? Between 1712 and 1870, interchangeable parts, bifocals, lightning rods, cotton gins, spinning jennys, carbonated water, thermometers, guillotines, parachutes, hot air balloons, sandwiches, mayonnaise, gas turbines, internal combustion engines, matches, electric batteries, microphones, typewriters, sewing machines, barbed wire, reflecting telescopes, stethoscopes, gyroscopes, mechanical reapers, corn planters, bicycles, telegraphs, postage stamps, photography, staplers, airships, gliders, light bulbs, traffic lights, Portland cement, the Bessemer process, and tin cans were invented. Watt's steam engine was an iteration, a few incremental improvements over Newcomen's design. And then most of the inventions that shape contemporary life came between 1870 and 1970.
