When the word “technology” is used today, it is most often used to refer to high technology – computers, cell phones, rockets – rather than technology in general. But when anthropologists use the word “technology,” they go all the way back to the controlled use of fire (from about 500,000 – 1 million years ago), the invention of the wheel (c. 4000 BCE), and beyond. The first technological tools were simple hand-axes made by our hominid ancestors millions of years ago.
The earliest technological divisions are from mankind’s early history, divided into the Stone Age, the Bronze Age, and the Iron Age depending on the primary tool and weapon-making material at the time. Each building material is superior to the one before it, but more difficult to develop requisite metallurgical techniques. The Iron Age began in about 1400 BCE.
Since the formulation of the scientific method in the 15th century, technological progress has apparently been accelerating. Some technologies developed since then include the telescope, the microscope, the clock, the engine, the electric generator and electric motor, radio, nuclear power and weapons, television, computer, and many others.
Technological development continues strongly today, fueled by the multibillion-dollar economies of the world’s most prosperous nations. The hottest developments in technology today are happening in computers, nanotechnology, materials science, renewable energy, entertainment, space travel, and medicine.
Philosophers as well as laypeople often debate whether or not technological progress is, on the whole, a good thing for humanity. On the pro-technology side of the spectrum are techno-progressivists such as transhumanists, on the anti-technology side are anarcho-primitivists, and Neo-Luddites.
