It seems to me that what separates us from the animals is the external storing of information. It seems that every event or process mentioned is a revolutionary way of doing that.
The aforementioned Agricultural Revolution was a basic, simple way to externalize and organize the way we harvested food. It also led, IMHO, to the concept of ownership.
The Industrial Revolution, which included mass production and the printing press (IMHO the first true mass medium) helped user in the Age of Enlightment. The first movable type press was used in the Song Dynasty in china in the 11th century.
As part of the Industrial revolution the concept of interchangeable parts was vital for mass production, first of firearms and munitions, then to other items. This again was a result of a new way to reproduce information, in the form of parts.
Along with the Industrial Revolution came railroads and telegraphy, then telephony. There was also newspaper,magazines, radio and television, the “mass media”, so-called because each medium was used to disseminate information to “mass” audiences.
Eventually the technologies of radio (including television) and telephony merged, and information was broadcast, first through the air, then through high capacity coaxial cables. (Interesting side note: the coaxial cable that attaches your TV monitor to your cable or satellite box uses technology that is over 100 years old!)
The military and space programs were significant in developing miniaturization and satellite communication, adding to the potpourri of technology we use everyday to complain that there’s nothing on my 200+ cable television package!
I think the next revolution will continue our externalization of information. In much the same way we can access the internet with pocket devices leads me to believe there will soon be some sort of wireless access to the human brain. Something like, but different from, Kurzweil’s Singularity.
@stanleybmanly Trump IS a revolution. I don’t consider him a revolution, although I do find many of his antics revolting!”
